my root filesystem is full. how can i fix the problem? i allocated 15G to root which i understand should be sufficient, i wonder if i have configured the partitions correctly. there might be a problem with the /snap directory.

here is the output of selected commands:

here are some things that i already tried, they didn't help:

sudo apt-get clean

sudo apt-get autoclean

sudo apt-get autoremove

sudo apt-get autoremove --purge

sudo apt-get remove --purge linux-image-X.X.XX-XX-generic # for old versions



sudo find / -xdev -name core -ls -o  -path "/lib*" -prune



erik@laptop:~$ dpkg -l "linux*{tools}*" |grep ^.i

dpkg-query: no packages found matching linux*{tools}*

i would be grateful for any assistance.

edit: this is how my drive appears in gparted:

screenshot

so it looks like i have a 256G m2 drive and i installed the boot, root, and swap partitions there, with leftover space mounted at /m2. my /home directory is on a separate device.

so if i can't fix whatever is wrong with root, i'm wondering if i could increase its size by 1) delete /m2 2) delete swap 3) resize root 4) recreate swap. would that work?

edit #2:

du -h /var/lib/snapd/snaps

erik@laptop:~$ du -h /var/lib/snapd/snaps

4.0K    /var/lib/snapd/snaps/partial

2.8G    /var/lib/snapd/snaps

Boot from a live distro, shrink p4 partition, move p3 next to p4, resize p2

i have a 256GB M2 drive on which i had installed boot, root, and swap, with leftover space mounted under /m2. then i have a 1TB drive on which i installed /home. snap filled up my /var directory.

i think the correct solution would have been to move /var to /home/var but i couldn't get that to work.

then i zapped swap and /m2, increased the size of root, and added back swap and /m2. but then i got errors relating to invalid sectors or corrupt disk, i can't remember exactly.

so then i stopped using the M2 drive altogether. i tried to shrink /home and to put boot, root, and swap at the end of the 1TB drive. but this got corrupted too. in the end i did a bare metal reinstall to the 1TB drive.
