On my Ubuntu 24.04 system I have all of the usual snaps installed by Canonical. I issue:
snap refresh --time timer: 00:00~24:00/4 last: today at 00:32 EDT next: today at 07:22 EDT
Whenever some other maintenance on my system requires rebooting, before starting up applications I issue:
sudo snap refresh
And then I sit back for a couple of minutes while snapd downloads and installs multiple snaps. I am particularly puzzled by Chromium. I never open it for more than an hour or so each day because I do not trust Alphabet. I do all of my work on Firefox. So why wasn’t Chromium and the other snaps updated?
