How to remove disabled (unused) snap packages with a single line of command?
I'll look into adding this sometime soon (as a 20% thing). Meanwhile, you could drop
#!/bin/sh
set -eu
snap list --all | awk '/disabled/{print $1, $3}' |
while read snapname revision; do
snap remove "$snapname" --revision="$revision"
done
into a shell script and run that.
I found more elegant and easy to use on an alias (using single quotes) this solution:
LANG=C snap list --all | while read snapname ver rev trk pub notes; do if [[ $notes = *disabled* ]]; then sudo snap remove "$snapname" --revision="$rev"; fi; done
Starting from snap 2.34 and later, you can set the maximum number of a snap’s revisions stored by the system by setting a refresh.retain
option (source).
sudo snap set system refresh.retain=2
The capability to purge/remove old/disabled snaps has been discussed previously but not yet implemented. In the meantime unfortunately it's a manual process.
