Backing up system packages

[grizzled tinsel]

My friend backed up my home directory to a diffrent drive, named home.ext4, my arch was broken thanks to windows. So I made two log files, Pacman -Q and flatpak list

I piped the output to the files I wanted, now I need a command to restore the packages, by installing them, from the log file, I have alot of packages so I'm not doing manual, also how do i account for dependecies

[safe prawn]

try to repeat the pacman -Q bit but with

1. explictly installed : pacman -Qenq > explicit.pacman
2. dependencies : pacman -Qdnq > deps.pacman
3. aur : pacman -Qemq > explicit.aur
4. aur deps : pacman -Qdmq > deps.aur

with this all you need to do to install is

cat explicit.pacman > sudo pacman -S --asexplicit -

cat deps.pacman > sudo pacman -S --asdeps -

cat explicit.aur > paru -S --asexplicit -

cat deps.aur > paru -S --asdeps -

and also the flatpak biut seperate runtimes and apps in flatpak
1. apps : `flatpak list --app --columns=application,branch | awk '{print $1 "//" $2}' > apps.flatpak`
2. runtimes : `flatpak list --runtime --columns=application,branch | awk '{print $1 "//" $2}' > runtimes.flatpak`

with this all you need to do to install is

flatpak install $(cat apps.flatpak)

flatpak install --no-auto-pin $(cat runtimes.flatpak)
```

@safe prawn I'm thinking about writting a script that looks at a packages dependencies then registers it under that package, later tho, currently ill do vista's thing then later the script will Uninstall packages meant as dependencies

I wish there was like a package manager for these advanced stuff

Thanks

[ripe brook]

vistaman received a thank you cookie!

[safe prawn]

don't uninstall

pacman -D --asdeps package-name

changes status of the package to installed as a dependency

[grizzled tinsel]

So to get it for flatpaks I change the pacman -S command?

That's iy

[safe prawn]

with this all you need to do to install is

cat explicit.pacman > sudo pacman -S --asexplicit -

cat deps.pacman > sudo pacman -S --asdeps -

cat explicit.aur > paru -S --asexplicit -

cat deps.aur > paru -S --asdeps -

[grizzled tinsel]

One sec

Uhh

I can't enable network manager

[safe prawn]

you don't use nm in the archiso

you use iwd

they have done that

[grizzled tinsel]

I enabled it

Already

[safe prawn]

anyways

do you still have access to your old arch system?

[grizzled tinsel]

I booted up in system

[grizzled tinsel]

No

[safe prawn]

have you formatted the old arch system?

[safe prawn]

if you haven't you can chroot into it and create the files i mention

enable doesn't start a service

[signal oasis]

yo do y'all need help

[safe prawn]

just tells a service to start at boot

[grizzled tinsel]

I reformatted it to delete the stuff, same computer, I broke it so I was booted into emergency shell

[safe prawn]

enable --now
makes it start at boot and currently

start just starts the service

[grizzled tinsel]

Bus

[signal oasis]

why not pacman -S --needed $(cat file.txt)

[safe prawn]

you are in a chroot

exit the chroot and use iwd

[signal oasis]

help explaining or dealing with anything

[safe prawn]

networkmanager is not availabel in the iso

use iwd as per install guide

[grizzled tinsel]

I rebooted onto my system after installing grub, ima send a vid

[signal oasis]

it is afaik

i might be wrong, maybe that was wifi-menu??

[safe prawn]

the hostname is clearly still archiso

[signal oasis]

what does ! $i =~ ^[0-9] mean

[safe prawn]

you need to parse it to not include package version

of course unneeded if it was the output of -Qq

[signal oasis]

so? you can still install??

[grizzled tinsel]

The usb is my ventoy drive I installed arch from

[signal oasis]

oh ig not nvm

mb

[safe prawn]

why not use awk to seperate each line using space as the delimiter and then use the first column

[grizzled tinsel]

Why is my arch system appearing as a iso

[signal oasis]

uh if you use "``" then it gets turned into space

btw use $(< file.txt) not `cat file.txt`

[grizzled tinsel]

Nmtui works

Mvm

[signal oasis]

hm

[grizzled tinsel]

Nvm

[signal oasis]

it just runs faster
ig you could use `` but most people don't cause its confusing

whatevs

yea ig

ok so whats the issue rn

[grizzled tinsel]

One sec

[signal oasis]

programming sucks sometimes

[grizzled tinsel]

I'll use this

[signal oasis]

sure

[grizzled tinsel]

I assume it's correct

I'm adding the -y flag

Heh

Tf happened

How do I check

Bin/bash

Got it

UGH

Y flag didn't work

What's the skip ask flag?

--noconfirm

Before -S?

Or after pkg nane

Works

Now time to wait and see

My friend made a ext4 file, how do you do that? Like my whole home was in a ext4 file

If somethings installed as a dependeny

And it comes up in the log

Will it install it again?

Shit uhh

It'll install kde

When it does

I'll need to make a script which reorganizes stuff

When a package is installed the whole dependency tree is right?

[safe prawn]

no

pacman has such things called "optional dependencies"

[safe prawn]

not if you use the --needed flag

[grizzled tinsel]

SHIT

Uhhh

Cntr c and add needed flag?

[safe prawn]

if pacman is still in downloading phase, it's safe to ctrl + c

[grizzled tinsel]

Actually can I reinstall all my packages cus it's nearly finished and this time add the --needed flag

[safe prawn]

why reinstall?

--needed is to avoid any redundant reinstallation

[grizzled tinsel]

Well most are already installed and I wanna delete all duplicates

[safe prawn]

no duplicates are made with pacman

[grizzled tinsel]

Is there any way to delete dupe

[safe prawn]

what happens is that things gets reinstalled

[grizzled tinsel]

PHEW

That's what I was worried about

[safe prawn]

--needed avoids unnecessary reinstallation
just doing the needed operations

since you'll be looping your list from pacman -Q, without --needed,
you are reinstalling may things too many times,
hence i recommended the --needed flag

this is a pacman thing, not a bash thing, dont' worry

what i meant with the awk thing btw

of course pacman supports not listing version at all

still applies

awk is a language mainly used for parsing text

yeah

all print$1 does is print the first 'column' by default space is the delimiter to seperate things

since packages are listed as
package-name version
in every line

as you can see, works just fine

[grizzled tinsel]

How do I add a user with a existing home directory

I saved my user dir

I need that for my user

[steep pagoda]

same username?

[grizzled tinsel]

Ye

[steep pagoda]

just add one without a home dir

and change the perms for the existing folder

[errant mantle]

Might I suggest that you consider aconfmgr as a potential option? This tool keeps track of modified files and file properties, in addition to managing syncdb and alien packages.

• https://github.com/CyberShadow/aconfmgr
• https://aur.archlinux.org/packages/aconfmgr-git

[grizzled tinsel]

I'll check it out

I should have used timeshift but that only preserves home dir

[grizzled tinsel]

Anyways I need a command which restores from flatpaks

[safe prawn]

you have flatpak list-ed your packages so

flatpak install --no-auto-pin $(cat flatpak-package-list-file | awk '{print $2"//"$3}')
