Updating snaps Script
Posted: 2020-06-07 00:31
Hi,
I made some scripts for manage control snaps updates packages you might find usefull if you use snaps.
update-snaps.sh
- Update one by one snap if there is any update available asking for confirmation..
- filteremove param: exclude packages to ask for update.
purge-snaps.sh
It holds automaticall updates for 60 days until next purge, and then remove/purge all disabled snaps (older retainned versions)
tell me if you see something wrong or anything to improve..thanks.

echo "Para Purgar : *****************************"
snap list --all|grep disabled
purge-snaps.sh
It holds automaticall updates for 60 days until next purge, and then remove/purge all disabled snaps (older retainned versions)
Code: Select all
#!/bin/bash
clear
#Hold 60 días
sudo snap set system refresh.hold="2029-04-23T17:22:54+01:00"
snap refresh --time
# Filtro paquetes que se quieren conservar versiones anteriores
filteremove="grep -v -e opera -e okular"
# Removes old revisions of snaps
# CLOSE ALL SNAPS BEFORE RUNNING THIS
set -eu
snap list --all | $filteremove | awk '/disabled/{print $1, $3}' |
while read snapname revision; do
sudo snap remove "$snapname" --revision="$revision"
done
, there must be some type of workaround to avoid any snaps be updated once holded time expire.
