All autopkgtests for the newly accepted systemd (248.3-1ubuntu8.5) for impish 
have finished running.
The following regressions have been reported in tests triggered by the package:

snapd/2.54.3+21.10.1ubuntu0.2 (s390x, ppc64el, arm64, amd64)
casper/1.465 (amd64)
tpm2-abrmd/unknown (ppc64el)
corosync-qdevice/unknown (ppc64el)
nftables/unknown (ppc64el)
udisks2/2.9.4-1 (arm64)
diaspora-installer/0.7.15.0+debian1 (arm64, s390x)
systemd/248.3-1ubuntu8.5 (armhf)
swupdate/2020.11-2 (s390x)
munin/2.0.57-1ubuntu1 (arm64, amd64)


Please visit the excuses page listed below and investigate the failures, 
proceeding afterwards as per the StableReleaseUpdates policy regarding 
autopkgtest regressions [1].

Title:
  systemd: autopkgtest: tests-in-lxd fails because of remaining snap
  .mount units

Status in systemd package in Ubuntu:
  New
Status in systemd source package in Impish:
  Fix Committed

Bug description:
  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.

  During setup for tests-in-lxd, an attempt is made to purge snapd, but
  this fails:

  dpkg: error processing package snapd (--purge):

  [ ... ]

  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.
