My system is running out of disk space very quickly

[fathom spruce]

I am using a machine that has an encrypted partition with LUKS on it. There are two partitions inside the encrypted logical partitions with Linux mint on it: a root partition of 185GB with 88 GB free and the home partition with 272 GB that is full. I am not able to open any programs asides from the system programs and I am not sure what is eating up my disk space. I have never encountered an error like this when I first installed mint. My suspicion is because of Python and docker because I tried installing them on the system and failed multiple times. What can I do to free up space without any loss of data or having to reinstall the entire operating system?

Maybe you have automated system snapshots with timeshift, and it automatically fills up the disk space.

[fathom spruce]

My system snapshots are saved to the root partition. My home partition is the one affected. Upon looking into the file system structure I found that in this path: File system/home/.encryptfs/(username) I found this in the properties tab. I am not sure if this displays the size taken or the total size but my home folder according to the df -h command takes this much space out of all the disk (second IMG)

[fathom spruce]

I have also gathered some info about the file system. Apparently, there are problems with the encrypted luks partition and docker desktop because when I have wiped the encrypted content that took the most disk space I ended up with 261 GB free out of 272. When I tried starting the docker engine again, on docker desktop I ended up with this amount of space free and a low disk space on root warning (4th image)

[crisp fable]

The encryption seems to be the problem.

[fathom spruce]

Further proof, this is the aftermath of trying to start another docker container

On my system there are 83.1 GB free out of 272

And this is taking the most disk size on the home partition

I am not sure if this is how Luks encryption should act normally or if I did something wrong when installing the os. I dual boot mint asides from windows and followed this tutorial in installing the encryption command by command

Ignore what I said about the 83 GB of free space, I think the error happened again and it took up all the space in the computer

boot into your linux, then do sudo apt clean && sudo apt autoclean && sudo apt autoremove

that will create some space. Secondly, launch "Disk Usage Analyzer" and see what exact folder is using up so much of the space.

and in that folder (in file manager) turn on details view, and see which file(s) are enormous

[fathom spruce]

these are my findings on the disk usage analyzer, this is part of the encryption on the home logical partition

[fathom spruce]

i will run that command when i boot into linux and ping you again

[limber vortex]

yes and use alt+prntscr to screenshot stuff when on linux, and logged into Discord. (use web browser if don't have discord app)

what you'll want to do is get info on that first thing in pic above which shows red, the first one under .Private . See what exact folder that is. taking up 281 GB

having 50 items

[fathom spruce]

Ran the command but it didnt do much im afraid. This is what I found that is the issue. A folder with an encrypted file of 281 GB

[limber vortex]

that's just an encrypted container showing your drive as one file

install kfind

and bleachbit (system app, NOT flatpak)

[fathom spruce]

Installed kfind

[limber vortex]

ok, open it

[fathom spruce]

I have removed the container too but when running docker my space got taken again

[fathom spruce]

I have opened the app

[limber vortex]

in the "look in" field, put /home/$user

then in its options, find all files (*) of size: (at least) 1 GiB

[fathom spruce]

Like this?

[limber vortex]

no

in named, put * ; in look in: put /home/youraccountname

and in the properties tab,

put the size to search for, "at least" 1 GB

[fathom spruce]

This is what it found

[limber vortex]

maximize the window

it should show the size in the results columns

or move the bottom scrollbar

[fathom spruce]

The size of that item is 3.9 Gib

[limber vortex]

pretty huge

that's just the deb package too. imagine once it installs and decompresses!

u searched by size as I said?

[fathom spruce]

Yes I did

[limber vortex]

you can also repeat search, and put search size "at least 400 MB"

you can also repeat search, but instead of size properties, do by 'modification or creation date' : last day, or last 3 days

and see what files got made in such timespan, and where they are found. that should give you hints on what is causing the issue

[fathom spruce]

Done that too now, just that 1 item showed up

In total the home folder is 10GB

Without the encryption

This is what I mean

[limber vortex]

do the thing i said about creation dates

asterisk (*) means all files

[fathom spruce]

I installed the os yesterday

[limber vortex]

well that's fucked

do this in terminal:

[fathom spruce]

I put the creation dates a few days ahead so that I am sure

[limber vortex]

lsblk -o NAME,TYPE,MODEL,LABEL,SIZE,FSSIZE,FSTYPE,FSUSED,MOUNTPOINT,OWNER

maximize window before hitting enter

[fathom spruce]

All in 1 go

[limber vortex]

yes all one line

and maximize first

then show it

[fathom spruce]

My terminal

[limber vortex]

look at the FSUSED column. I don't see any problem

mark that command down somewhere safe, and use it from time to time

you can also make an alias,, like lsblkk that equals the above exact command, so it's shorter to use

i mean you obviously must have installed a lot of stuff in just one day in order to have (84 + ~10GB) 94 GB already used up. A clean linux install only uses up about 10 GB.

[fathom spruce]

My home folder without the encrypted garbage has 10GB taken

[limber vortex]

I dont need to see that. i see everything I need to know from lsblk -o

[fathom spruce]

OK, in that case I think it might be mainly from docker and Python. I don't think there is much more installed

Because when I start docker my disk space gets eaten up

[limber vortex]

then it's fucked

[fathom spruce]

What is fucked?

[limber vortex]

docker

[fathom spruce]

So docker is broken not Linux

[limber vortex]

seems like

[limber vortex]

alias this command, and you will always have it handy

[fathom spruce]

Might want to go on docker support or reinstall docker in that case
