when I installed debian 12.7 I created a separated /var directory, along other 2 separated directories (names forgotten).
I also use flatpak and this program is installed in this directory. Executing ‘flatpack update’ I discovered this directory is 95% full, meaning I cannot update anything, because /var is 95% full (only 400 MiB free)
Ideas to solve this?
In the future, you should look into using LVMs for your partitions.
I ran into a similar problem recently where my /var needed to be increased - I was able to run a simple lvextend -L+4G /dev/myvg/var --resizefs
to grow my /var by 4 gigabytes.
Before I was using LVMs though I used a gparted live disk a lot
