[Bug 2097700] Re: Software Updater fails to update snaps

[Mika Haaja]

Hi.
I have also noticed this bug myself. I suspect that the App Center switched to the snap version has something to do with it. However, I was not able to fully test this, because the deb version is no longer fully supported in newer Ubuntu versions.
I installed the "gnome-software" and "gnome-software-plugin-snap" deb packages into a virtual machine with Ubuntu 24.04.2. In this case, running Software Updater also didn't check for snap updates.

If Software Updater also would update snaps, it would fix the long auto-
update delay for some snap applications on computers that are rarely
powered on. Then the snap applications would update at least once a
week, or on the first startup if computers are used even less
frequently.

I followed this long auto-update delay for Firefox and Thunderbird in this bug report.

Title:
  Software Updater fails to update snaps

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  Software Updater (update-manager) updates APT packages as expected,
  but in the end it says "updating snaps" and this takes a while, but it
  doesn't do anything. I have to manually update snaps by running "snap
  refresh" separately.

  I expect it to update snaps as if running "snap refresh", or not even
  try and avoid wasting time for nothing.
