Hello guys, thanks for the help and your time before starting.

My problem is this one:

I have Debian 12 installed onto my computer with 4 partitions:

Total disk is 466,6 GiB (~=500 GB)

• "/"           Size: 22,7 GiB  (42% used)

• "/tmp"        Size: 1,8 GiB  (6% used)

• "/var"        Size: 9,1 GiB  (84% used)

• "/home"       Size: 433 GiB  (12% used)

"/var" is almot full, with a 84% used, and I want to try to decrease that percentage. I've removed logs and all I could remove, but that percentage is still pretty high.

Searching around, I found that apps installed through Flatpack are stored in "/var/lib". This may be my problem? Is there any way to store Flatpack apps on "/home"

Solution -------

Thanks to @furrowsofar@beehaw.org and @heartlessevil@lemmy.one

To solve this I moved "/var/lib/flatpack" to "/home/user/..."

Then I softlinked the folder to its previous place with the next command:

ln -s [source || /home/user/.../flatpak] [Destination || /var/lib/]

I reduced the storage percentage to a 18,5% :D

Edit: corrections
