The package name is just "linux"
Okay so going to bet soon but basically you want to:
- install the "linux" package
- update your bootloader configs however you first set them up so that the latest kernel is an option
- reboot into latest kernel
- install linux-headers
- install the rtlwifi-new package from before
obsidian light
I don't even think it's grub. I can't find what it is

Does anyone know of a good screenshot tool that works well for ubuntu/kde neon? I need to be able to select an area to screenshot, and if I can upload to imgur with it, that's a plus
i get random grey blocks covering the image with shutter
Looks like kazam works but if anyone knows of one that lets you upload to imgur as well as select an area, I'm all ears
main olive
@granite abyss spectacle works great with KDE (I think it's a KDE tool?), allows you to select areas (as well as active windows etc) and upload directly to imgur

Hmm I don't think that one worked for me
Oh actually I can select a region

Unix is an early Linux?
gilded basalt
It came before Linux
Unix has been around since the 60's
Linus Torvalds made Linux in the early 90's as what started as a personal project based on Minix, which was a variant of Unix designed for educational purposes
People thought it was interesting, so he threw it up on a FTP server for people to get it. A lot of people started using it and contributing fixes and code back to Linus.
It rapidly snowballed and is now the most widely used OS on the planet
spice relic
thanks for the history lesson!

So, I was reading this: https://superuser.com/questions/739736/apache-as-reverse-proxy-for-multiple-destinations-and-one-default-destination
I am not convinced that it solves my issue. What I need is to proxy any url of my choosing from http to https. Mostly streams. Is there a way to achieve that with Apache reverse proxy?
Without restarting the server, I might add
I can't seem to be able to wrap my head around it
Maybe I describe what I have in mind: Have a Virtual Host running on [::1]:80, which runs with SSLEngine On and the URI should look something like: https://[::1]:80/theother.example.com/stream.mp3, streaming the content to https from a non https source.
Or maybe someone knows a different solution, idk
main olive
nginx reverse proxy.
for streaming things, you should add the rule proxy_buffering off;
you'll want to extract the URI and pass that as a variable, so probably something like
location ~ ^/(.*) {
proxy_buffering off;
proxy_pass http://$1;
}
if i've got this right
(alongside your ssl-related rules of course)
steel verge
Thanks, but my whole project revolves around apache, switching to nginx before I really have to would require 2 days work at least
main olive
not too familiar with apache, sorry
but some googling tells me you cah achieve this with a mod_rewrite rule, something like this
RewriteRule ^/(.*) http://$1 [P,L]
@steel verge
no idea if this would work or if it's even valid syntax
this has some very serious security implications, though, and i hope you never allow public access to this
steel verge
Yep, that did the trick, combined with proxy_pass
thanks mate, you saved me lots of headache, I hate rewrite rules
<VirtualHost [fc00::1]:9999>
SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/internal.tuxstash.de/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/internal.tuxstash.de/privkey.pem
RewriteEngine On
RewriteRule ^/(.*) http://$1 [P,L]
ProxyPassReverse / http://$1
ErrorLog ${APACHE_LOG_DIR}/proxy.error.log
CustomLog ${APACHE_LOG_DIR}/proxy.access.log combined
</VirtualHost>```When I now visit https://proxy.internal.tuxstash.de:9999/br-edge-100b-fra-dtag-cdn.sslcast.addradio.de/br/br3/live/mp3/56/stream.mp3, it properly plays the stream on https
Now Chrome can suck it π
Regarding security: I don't think it has that serious implications. It is a separate virtual host and nothing else is there. The rest of the system is still safe. I need to do it though, because German radio stations are too stupid to implement proper TLS and I need my app to continue to work with the new rules on Chrome @main olive
main olive
it has the same implications as any open proxy does, ie it can be abused by whomever to do evil things. Additionally, since this is a pretty iffy way of doing, it, you could do things like reverse proxying to localhost to access services running only on the loopback interface, which you probably definitely don't want
steel verge
Oh that. Yeah, I will have to find a way to wall that off and only allow domains I want to have there, but for now I got a working solution.
I can probably do that with a htaccess or something

"beginner" distros include debian, sometimes fedora, but mostly ubuntu
blazing wolf
yea im using ubuntu mate now, due to some issues im switching to open suse
i am going to try it out in the virtual box first
steel verge
Debian is really not a good desktop distribution
Depending on what you want the Linux Experience for, I'd go with Ubuntu for private and Fedora for professional experience
Reason being, that businesses mostly use RHEL and Fedora is as close to RHEL as it can go, save CentOS, which is not recommended for Desktop either
Fedora has the caveat of not having a lot of packages readily available and you need to install more sources to get newer packages
@blazing wolf
steel verge
I personally don't like SuSE even though I am from Nuremberg
But, that is a personal preference

debian is fine for desktop

I didn't say it does not work, I am just saying that Ubuntu offers the better experience and deep down, it is still a Debian π

hi guys i am bit a noob on linux. Could you guys let me know how to close vs code from terminal (without using pkill electron)??
some other ways!!
using ubuntu 18.04*
warm wolf
killall code?
main olive
here's a oneliner which kills only code and leaves other electron processes intact
kill $(ps aux | grep "electron.*code.js" | head -n1 | awk '{print $2}')
main olive
pgrep does not exist on my system
oak shell
what system is that?
main olive
gentoo
main olive
... in any case, there's nothing wrong with using my ps|grep for this if you don't have pgrep or pkill
of course, prefer the latter if you can, but he specifically said "without using pkill"
oak shell
"without using pkill electron" if we're gonna quote things
main olive
:l
oak shell
my response would be pkill -f code.js or so, depending on how the command line for vsc looks exactly
main olive
something like
/usr/lib/electron6/electron --no-sandbox /usr/lib/code/code.js
and head -n1 is wrong, I think? You use that to filter out the grep process, I assume, but as ps is sorted by pid, this fails if your code process has a higher pid than grep, which happens once the pids overflow and start over.
would rather need a grep -v grep or so, I believe
which is one of the big problems with ps|grep
and it's not atomic
main olive
ps aux --sort=lstart
then
oh, hm, this doesn't take date into consideration
apparently

complexity increases

what exactly does the yum update command do?
nvm
yum install package_name
Used to install the latest version of a package or group of packages. If no package matches the specified package name(s), they are assumed to be a shell wildcard, and any matches are then installed.
yum update package_name
Used to update the specified packages to the latest available version. If no packages are specified, then yum will attempt to update all installed packages.

Hello there,
I've a problem regarding the installation of the python module aiodns (I'm in a venv environnement in 3.7 using pyenv):
I installed it via pip and it looked fine:
Successfully installed aiodns-2.0.0
However when I try to use it in my project I get:
RuntimeError: Resolver requires aiodns library
π€ So I tried to import it in shell, and here is the problem:
ImportError: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.28' not found (required by /home/pi/D/my_venv/lib/python3.7/site-packages/pycares/_cares.cpython-37m-arm-linux-gnueabihf.so)
I did not delete the folder @sage solar before reinstalling python 3.7 with pyenv because it seemed to rewrite the folder, could it be the cause of the problem?
main olive
you probably just need to upgrade your distro's glibc
looks like CPython was built with 2.28, which is (maybe probably) newer than what you have
@frank coral what does ldd --version say
main olive
what distro are you running anyways?
warped nimbus
raspbian my guess
frank coral
(Debian GLIBS 2.24-11+deb9u4) 2.24 (raspbian)
main olive
well... there you have it
my suggestion? compile a newer glibc manually and point to it via LD_LIBRARY_PATH when running anything requiring pycares
maybe the unstable repos have a newer libc?
frank coral
that sounds like out of reach for me now ^^" Maybe downgrading aidons could works?
main olive
looks like it's an issue with pycares, which is a dependency of aiodns
frank coral
Yep, but downgrading aiodns will downgrade its dependencies requirement, doesn't it?
frank coral
I do need to uninstall all its decencies as well before downgrading, no?
main olive
depends on whether it's listed as >=version or what, but I'd say yes just to be sure
frank coral
picards 2.4.0 still needs GLIBC_2.28
I'm slowly downgrading testing every combination...
@main olive I tried v 1.0.0 and it still needs GLIBC_2.28 but this version was released in 2015, is it normal? It looks to me that pycares is not well uninstalled
main olive
seeing as 2.28 wasn't even out in 2015, I wouldn't say so :p
frank coral
Well what I've done is fully removing aiodns from my code and it works...
main olive
just a thought - latest raspbian (buster) uses 2.28
tried upgrading?
it's fairly simple - https://pimylifeup.com/upgrade-raspbian-stretch-to-raspbian-buster/
frank coral
@main olive Maybe pycares in 3.7 needs it? Or uninstall pycares does not remove it completely
main olive
couldn't really say tbh, I'm not too familiar with pycares, sorry
frank coral
neither I am lol
But because it have C dependencies from what I've seen, pip may not remove it entirely
frank coral
I think I'll need to, my current distrib' only support postrgesql 9...
main olive
π more the reason to
frank coral
and 3.7 will be supported natively

@frank coral let me know if you run into any issues while upgrading

yea i got that but generally for installing?
like i have to do sudo python3.8 -m pip install pipenv

are you installing it to use it user-wide or as a project dependency? @blazing wolf

pipenv is for user-wide
not sure if im gonna need any tho
but in general how can i remove root user access for commands(specific commands)?

just don't run those commands with sudo?

it wont let me

pass the --user flag to pip to do a user-local install, rather than a system-wide install

Hello
I need help with only displaying the error message from a mkdir command
i only want it to display the error message as the output
mkdir -v /tmp /tmp/test
warm wolf
Then take off the verbose flag
tranquil steeple
its for an assignment and i have to use that command
i cant get it
i tried to pipe it into grep
but it still displays the whole line
warm wolf
Redirect 1>/dev/null? Bit silly though, why can't you just take off -v?
tranquil steeple
/dev/null is the black whole of the Linux filesystem. It discards whatever you write to it. Sometimes you only want to see the error messages or the successful output. Show just the error messages from mkdir -v /tmp /tmp/test.
i have to right the command that will do this
^^^^^
i thought it would be something like this
mkdir -v /tmp /tmp/test | grep " "
and put the error characters in the quotes
warm wolf
Yes that's exactly what I wrote, 1 is the stdout stream, if you redirect it to /dev/null you only get stderr outputted
warm wolf
No it's not a command, you don't pipe to it

Anyone able to help me out with a VIM issue? While working I will end up with a number of open buffers. I then decide I need to open another file and immediately hit Nerdtree. Once Nerdtree is open I realize that the file is already open in another buffer and so I immediately switch to that buffer to find that the Nerdtree is replaced with the buffer. What I would prefer is that Nerdtree closes and that my main buffer switches. Does that make sense?
warm wolf
Try reading this https://en.wikipedia.org/wiki/Redirection_(computing)#Redirecting_to_and_from_the_standard_file_handles @tranquil steeple
tranquil steeple
ohhh
so i could do
mkdir -v /tmp /tmp/test 2>/dev/null
2 so its filters standard error

warm wolf
What do you mean, is that a question?
main olive
im trying to automate ftp using bash script but im having a error in the ftp command itself
@tranquil steeple you are redirecting stderr (numerical value of 2) to /dev/null
stdout, which is where standard output is usually put, has a numerical value of 1
I really don't understand why you can't just remove the -v flag
HOST=' ftp 10.1.1.1'
USER='name'
password='pass'
FILE='nmap.txt'
ftp $HOST <<END_SCRIPT
user $USER
$PASSWORD
pass
put $FILE

your command gets expanded to ftp ftp 10.1.1.1

the remote user's password that you're trying to ssh into
ah ok
might have to do it tomorrow though
the other computer is being used right now
I'll notify you tomorrow if that's okay

i see, so you know most of it right now but you got comfortable with it much quicker

guess so

i see, i'm still quite new to it, however i really love how much easier it is compared to windows, i just need to remember the name

instead of going trough sites and sites

@wild kraken software updates are much easier, ye?

yeah just a single command 
i'm still setting up the stuff i had in my debian

yea do the journalctl command to see what happened

is there a listing for www-data in /etc/passwd
alternatively, does sudo -u www-data /bin/sh work
if not, the www-data user is missing
you can either create the user or change the nginx conf to use another user, such as nobody
wild kraken
@main olive it was an error on my side
i had to change some stuff in nginx.conf
to work with my site
user www-data; was unnessesary for this version of nginx as it seems
main olive
it's not unnecessary, please don't blank it out
that will run nginx with root privs and it won't deescalate itself
which you very much don't want
set it to nobody nogroup
or just nobody
wild kraken
alrighty
worn apex
@wild kraken did you literally type "user@host"?

..y.. yes

yes

lol it wants the actual username and actual hostname, domain name, or ip address of the machine you're ssh-ing into

Hmm, I am a bit in a trepedation. This is not Python related, so if you want me to fuck off, just tell me. But I need to benchmark several nginX servers. Does anyone know a good tool? I have tried Locust.io, which is written in Python, but I am not sure I understand the usage correctly. What I need to know are two things: 1) how many users can concurrently visit the servers without it breaking down 2) which part of the system would benefit from an upgrade, either RAM or CPU. If I just send 100 users onto the server, half of the connections just fail. How do I use this tool correctly to get the sweet spot? If anyone has experience with it, I'd appreciate some advice.
Current config: 2 nginX with PHP-fpm, MariaDB, running a CMS, 1 Load Balancer with haProxy, both webservers firewalled off, only way to get to them is to visit the load balancer which is using round robin for balancing. So, pretty standard. 3 Dell RX470 Servers

EOT``` why $@ commands error when they try to read stdin? If I put $@ before timeout block, it can access stdin
oak shell
why are you putting stuff inside that shell and function anyway and not directly?
also you should always quote "$@", otherwise the individual arguments will be subject to word-splitting again.
split pulsar
real script has a few more opreations, I excluded them, but this example still reproduces problem for me
"$@" breaks everything, it tries to run several things as one command ("python main.py" not found)
oak shell
well, sh <<EOT is a here-document. You pipe the contents before EOT into the stdin of sh.
hm?
split pulsar
how I could rewrite this? move this block of code to function?
oak shell
have you tried with bash instead of sh? Maybe sh understands $@ differently...
split pulsar
I don't have bash in some containers. This script should be able to run everywhere. I run it in docker
I think "$@" works outside of this timeout block, but I need it inside
oak shell
sorry, I'm confused. Guess I'm missing whatever is wrong too. π€ I'm mostly used to bash anyway.
steel verge
Put the content of $@ into a variable, then access it later
split pulsar
will it fix stdin problem?
frank coral
Hey, do you have an idea of how much space is needed to install and run an image using docker? I think itβs about 2Gbm, am I right?
steel verge
Well, it will save whatever was passed to the script, not sure what stdin issue you mean. But calling another command clears the content of $@
split pulsar
it seems like $@ gets evaluated and replaced before I call another command
oak shell
how much space is needed to install and run an image using docker?
depends on your image. Some are few MB, others a couple GB. There is no general answer.
frank coral
Well docker itself is pretty heavy, isnβt it?
oak shell
The $@ in your script should get evaluated in your main script, because it's in the here-doc. So it gets the args passed to your script file, I believe.
split pulsar
maybe I could pipe my string script from the other side? xargs or something
without <<
oak shell
the docker daemon itself is not too heavy. Couple hundred MB all together. But downloading containers, their cache, volumes and logs can quickly grow large.
frank coral
I think Iβm going to start from a ubuntu image, because debian is quite conservative, but itβs a lot more heavier
uneven silo
what
oak shell
I am not sure what or why you are asking. If you want to build lightweight containers, you should start from light and container-optimized base images like Alpine, or even better use from scratch or truly minimal base images that only contain the runtime needed for your project (e.g. a JRE) if necessary.
frank coral
Ty
To be clear, Iβve 600mb left on my disk (Sd card), and Iβd like to know how much space does take docker + an image with some very basics tools (such as postgresql, python...), to buy a SD card with enough space.
oak shell
very basics tools (such as postgresql, python...)
that's not basic at all. Also storage is cheap these days, don't save on that if you buy one anyway.
frank coral
Well by basic I meant that they donβt really take a lot of space. Ty
oak shell
I meant the same.
frank coral
Wow, 32Gb about 6$, space is a lot more cheaper than 5 years ago or so (last time I checked)
oak shell
yeah, don't go lower than that. Better double or more and have some reserve. Also gives you more space per dollar.
frank coral
64Gb seems to be the best space/price ratio, but itβs no more related to Unix. Have a nice day
worn apex
@split pulsar in a standard conforming shell, "$@" [and "${array[@]} for array variables] is an exception, it still gets split as long as the values were separate arguments in the first place
only "$*" will turn them into a single string
split pulsar
sh: 5: python exec_input: not found
this happens after adding quotes
python exec_input is my command in $@
worn apex
@frank coral 64 GB you have to start thinking about compatibility, not every device/software supports SDXC/exFAT, and 32GB is the largest for SDHC
@split pulsar how did you run the script?
split pulsar
it's docker entrypoint
worn apex
i am asking how you passed "python exec_input" to the script
the question is really whether that had quotes around it going in
split pulsar
it is argument to docker run
worn apex
i.e. sh foo.sh python exec_input or sh foo.sh "python exec_input"
ok what is tyhe full docker run command then
split pulsar
ENTRYPOINT ["run_entrypoint.sh"]
CMD ["python", "exec_input"]```I haven't found a way to not use it. I can't just call function defined above
worn apex
yeah but there's a way to do it, hold on
split pulsar
I'm currently trying to use sh timeout ... sh -c " ... " but I get weird errors
at this point I'm considering moving entrypoint logic into application
worn apex
ok i found the right way to do it
#!/bin/sh
timeout --preserve-status --k=1s "$TIMEOUT" sh -s "$@" <<'EOT' || exit_code=$?
run_user_code() {
"$@"
}
run_user_code
EOT
though honestly I don't get why you need to do all that instead of just
timeout --preserve-status --k=1s "$TIMEOUT" -- "$@" || exit_code=$?```full code is here https://github.com/IOMirea/run-runner/blob/master/build/run_entrypoint.sh
I'll try that snippet in a moment, thanks
worn apex
i.e. why does this need to run in a subshell and have a function at all
oh
ok well yeah
you probably need to export COMPILE_COMMAND too for this approach
i gtg, be back later
wait nevermind, it's already coming in the environment
anyway, the basic approach of sh -s "$@" (or sh -s -- "$@") and using <<'EOT' instead of <<EOT is the important part, variable expansion needs to happen inside the subshell
split pulsar
I posted full script. All I changed was using -s "$@" <<'EOT' and adding quotes around $@
my initial problem was that any code inside timeout block can't access stdin
worn apex
are you sure docker passes stdin to the script at all?
what happens if you run the script directly
split pulsar
yes, commands work outside of this block, I'll try to run it manually now
the same happens when I run it manually
"$@" is empty
this is probably because I use it in function. it has no args and $@ gets overriden
without quotes it gets evaluated before function starts
I'll just move timeout to application. This is not worth it
main olive
@split pulsar haven't really read any messages after your script but
$@ in a function takes params passed to the function, not the script
if you want to pass stdin to the function within the script, call the function with run_user_code $@
actually, no, you can't pass stdin like that at all
need to read from filestream 0
ie <&0
worn apex
lol i can't believe i didn't realize that
incidentally i figured out the stdin problem
<&0 won't work either, incidentally
I think this will work, your problem is that the <<EOT overrides stdin.
script='set -e
run_user_code() {
$COMPILE_COMMAND
"$@"
}
if [ -z "$MERGE_OUTPUT" ]; then
run_user_code
else
run_user_code 2>&1
fi'
timeout --preserve-status --k=1s "$TIMEOUT" sh -c "$script" x "$@"
exit_code=$?```@split pulsar
i might do this instead, to simplify the inner script as much as possible ```sh
if [ -n "$MERGE_OUTPUT" ]; then
exec 2>&1
fi
script='$COMPILE_COMMAND; "$@"'
timeout --preserve-status --k=1s "$TIMEOUT" sh -e -c "$script" x "$@"
exit_code=$?
now there is a weird problem, stdin goes into stdout if not consumed, all \n are \r\n now
anyway I'm rewriting this in python
split pulsar
oh, these are fixed, it was caused by --tty docker flag
@worn apex thanks! this part of code was a headache for a few days if not weeks for me

how about ls again, what do you see in your home directory?

sorry, what distrobution of linux is this

ubuntu, arch, debian, etc
native sluice
Oh yeh Ubuntu
native sluice
Itβs a server
stone pier
gotcha, can you do lsb_release -a?
native sluice
Lemme try
stone pier
it's possible that the server version doesn't include a Downloads directory by default
stone pier
lol
native sluice
No LSB modules are available and the it said some info
stone pier
yea that warning is fine, i get that too
native sluice
Ok
stone pier
the info is what i care about

it doesn't say anything after the LTS part for Description?
native sluice
Nope

ok cool, let me google something, and while i do that, can you just tell me why you're trying to navigate to that directory?
native sluice
Erm yes Iβm trying to get golem setup with it
Itβs a thing that uses your CPU power to do stuff and you get money for it
stone pier
oh, doesn't really have anything to do with python development then
did you download some install file and can't find it?
native sluice
No I need to install it first

what do you expect to be in the Downloads directory?
native sluice
It says I need to be in the downloads directory to start the downloads
stone pier
can you link me to where it says that?

I started doing it in the normal dir but it would not work so I YouTubed the issue and got this

can i get a timestamp?
native sluice
Yh gimme a second
sterile dragon
2:40ish by the looks of it
native sluice
2:19
stone pier
ah ok, so it's as i expected
native sluice
Thatβs the error for the thing I got then he said I need to go into downloads dir which did not work
stone pier
yea, it doesn't matter what directory you do it in, you just need to be in the same directory as the install.sh file in order to run that specific command
otherwise you can provide the full path
all they're doing is making the file executable, and then executing it
do you have that install.sh file downloaded somewhere? like did you download that file?
native sluice
No, do I need to install that first
stone pier
you need to download the file so it's stored on your server. After that, you would make the file executable, and then run it in order to install
are there are instructions for downloading the file itself?
stone pier
around 1:26 in the video you see them downloading the file in a browser
i assume you're using a headless server, so you need to use a command to do it
you can copy the URL he clicks to download it, and do wget <url> replacing <url> with the one you copied
that would download the file
stone pier
no problem
native sluice
Ah
stone pier
for future reference, i would avoid coming to this server for help of this nature, as it has nothing to do with python. Even though this is the unix channel, it's still predicated on the idea that you're doing something python related

hello! I have been thinking about switching from windows 7 to some Linux OS ,maybe Mint - my question is as follows:
See..I host a discord bot on my laptop - do not ask my why and tell me other solutions - what are the differences between python on linux and on windows 7? I want to have my bot 24/7 online.

I have been installing linxes and oss before so I know to do that part.
Please ping me.

@main olive The differences between the two regarding Python code are minimal.
The only huge differences you'll find are going to be if you're opening files from your code, as your file paths are going to be different as are how you call them
Which could be mitigated if you use something like pathlib
Only other big thing that stands out in my mind is remembering to do python3 instead of just python, as calling python in either Linux or Mac will open up Python 2
Since they come with both

Linux probably has much better security than this windows 7 that refuses to update for months

quaint mirage
tbh if you're using one of the main distros with a nice installer there's really not much you need to do
if you are manually installing it and setting the advanced options by hand there are bits and pieces you'd perhaps want to do
seperate partition for tmp / home perhaps
swap partition
that type of thing @main olive
again, most of this is done automatically in a lot of linux distros
main olive
I have been thinking about Mint perhaps,and yes,I meant on swap partition !
Thanks again,now I know at least what to look for
@quaint mirage

it's basically like a page file for windows

with 8gb of RAM i can't see your swap being used too much either
also, you can create / destroy / mount / flush swap whenever you want on Linux

it's not an install time process
main olive

are you completely uninstalling windows?
main olive
Yeah,why not? I will be storing my files on a usb
quaint mirage
okay so yeah. backup your files somewhere and triple check to make sure they're backed up and then check some more that you got everything
then just full format the SSD and start from scratch
the linux installer should give you the option to remove all partitions
then just create a new partition
main olive
Or to be secure I could do my thing and copy-paste and then format,right?
quaint mirage
i mean yeah, as long as you don't accidentally break your new partition during the linux install
or remove it, rather

Please help me
oak shell
seems like you ran sudo pip install ... at some time, or messed up ownership in another way
with pip, always use sudo -H
to fix ownership and give it back to your user instead of probably root, run sudo chown -R $USER: ~/.cache/pip
after that try your installation again
@main olive
oak shell
well, you must not change owners of system files
main olive
I did that to /usr folder
oak shell
as long as it's inside your home directory (~) it is safe to make yourself the owner.
oak shell
yeah chown on /usr kills it
main olive
π€£
oak shell
gotta be careful not to typo there π
oak shell
I had to run it as root - Pycharm
god, no
don't run things as root arbitrarily
especially gui applications and such are not meant to run as root
not to mention the security aspect, that is exactly what is breaking correct ownership of files and leading to permission issues in the first place
Maybe sudo chown -R $USER: ~ to set ownership of all files in your home folder back to you, and then no more sudo for things that aren't supposed to run as root
uhm.. did you forget an import pytesseract or something?
dunno that library, but that error doesn't seem os-specific
you need the tesseract-ocr package installed on your system, but you don't have to set that variable because the default will be just tesseract and should work fine
you can try which tesseract in your shell to find the full path, but it should not be required to set that, if you can invoke tesseract directly on the shell (which means it's on PATH).
that depends on how you imported it
gah, please stop using all these star imports. that hurts
but there is no import pytesseract anywhere to see?
you clutter your global namespace with tons of names that are not used, and which might even overwrite each other
no need to apologize, such things happen to all of us.
see e.g. https://www.geeksforgeeks.org/why-import-star-in-python-is-a-bad-idea/ or any of the many more articles about it out there
if you have terribly long package names, you can do import pytesseract as tess for example
or you can explicitly import only the parts you want from a package, like from concurrent.futures import ThreadPoolExecutor

@quaint mulch no,sorry..I did use that module/library you mentioned,but I do not remember if it was on Linux and I did not have any problems.
@oak shell what do you mean?
I did that to the project folder
did not worked
I ran as sudo - everything works
PyCharm
oak shell
running pycharm as root is terrible
if things don't work as your user, that means you screwed up permissions or ownership somewhere - probably by having run things as root before that should not
do sudo chown -R $USER: ~, then start PyCharm normally as user, without sudo. What exactly happens then?
main olive
I have told you π But now when you are interested..I will again tell you
So basically when I open pycharm - I have to import modules(for example discord.py) and When I do so it says that
I have reinstalled Ubuntu 3 times today and every time I could not get it working
Sooooo no,I do not think I did screw anything up..yet
oak shell
how do you install modules? and to what interpreter?
main olive
What interpeter? python3.8, but it does not work - error linked in the link.
oak shell
because PyCharm can not install modules if you selected the system interpreter directly, instead of creating a virtualenv/pipenv/whatever
oak shell
settings -> project -> project interpreter
oak shell
okay, that works
oak shell
but that has nothing to do with pycharm then if you install manually using sudo -H pip?
main olive
but NO ANSWER online
I guess
I mean I linked my problems describing in more detail,so please take a look at that.
oak shell
or you have Python2 or any other interpreter as default for your project in PyCharm, instead of the one you installed packages for?
