I hate the small disks, it blocks apt update/upgrade commands usually.
# Top 20 largest folders (directories, i was windows guy) du -a | sort -n -r | head -n 5 # Top 20 largest files in home folder (directory) du -a /home | sort -n -r | head -n 5 # My favorite: du /* -hsx | sort -rh | head -20 # take a look at /tmp ls -lah /tmp # Kernel directories are another suspect. # Check your kernel version uname -r # This folder is probably a culprit. du /usr/* -hsx | sort -rh | head -20 ls /usr/src -lah
If your problem is excessively space occupying old kernel versions: Consider getting rid of the ones which are older than your kernel appropriately.
du -> sort command may fail if there is 0 space.
