[Bug 2036765] Re: ubuntu-release-upgrader failed to upgrade snap to track new release

[Brian Murray]

There is also an when refreshing firefox:

refreshing snap firefox
error: cannot perform the following tasks:
- Setup snap "firefox" (3145) security profiles (cannot find installed snap "firefox" at revision 2517: missing file /snap/firefox/2517/meta/snap.yaml)
- Run post-refresh hook of "firefox" snap if present (run hook "post-refresh": cannot perform operation: mount --rbind /dev /tmp/snap.rootfs_TbK5Bd//dev: No such file or directory)

And the firefox snap is still tracking a 23.04 channel:

Title:
  ubuntu-release-upgrader failed to upgrade snap to track new release

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  When upgrading Edubuntu 23.04 to Edubuntu 23.10 via `update-manager
  -d`, it failed to stop the snap-store and refresh it to track
  latest/stable/ubuntu-23.10 and was left still tracking
  latest/stable/ubuntu-23.04.

  This is problematic as, if ubuntu-release-upgrader cannot stop snaps
  to upgrade them during the upgrade process, then snaps will be stuck
  tracking old versions.
