This appears to result in some snap .mount units being left over in /etc/systemd/system. These leftover mount units will now always fail because snapd etc. is no longer installed. Thus, the 'test_no_failed' test, which checks for any failed units after boot, will fail:

The underlying snapd bug appears to be related to bug 1903967 and bug 1950864. In the mean time, the test should be fixed so this does not block systemd autopktests.
This build log provides an example of the problem: https:/ /autopkgtest. ubuntu. com/results/ autopkgtest- impish/ impish/ ppc64el/ s/systemd/ 20220331_ 190433_ fdbbe@/ log.gz.
