Save Space On Ubuntu - “SNAP” Folder Takes Space Fix

List them to see:

sudo snap list --all

Remove the old versions:

sudo snap remove <package> --revision=<old-revision>

For example in my case:

I will delete these:

sudo snap remove chromium --revision=2897
sudo snap remove code --revision=163
sudo snap remove cups --revision=1052
sudo snap remove gnome-46-2404 --revision=39

Script to Automate Removal

for snap in $(snap list --all | awk '/disabled/{print $1, $3}'); do
  sudo snap remove "$snap" --revision="$3"
done

Clean up cache:

sudo rm -rf /var/lib/snapd/cache/*

You can also use this command to check whats taking up space:

du --max-depth=1 --human-readable / | sort --human-numeric-sort

These steps should help you to reclaim disk space on your Ubuntu server by removing old and unused Snap versions!
