@laney Thank you for looking into the problem.

I will mark systemd-fsckd as flaky and look into the root cause later.
It used to be flaky before as well.

I have checked the last 10 failed runs from
http://autopkgtest.ubuntu.com/packages/systemd/hirsute/amd64 , with the
last one being from 2021-02-24 09:15:57 UTC:

As you can see systemd-fsckd has been skipped in 10 out of 10 runs, but 
"upstream" test timed out in 7 out of the 10 runs.
If you would like to help improving the failure rate caused by the 
infrastructure please run the systemd autopkgtests on bigger VMs.

Bug description:
  Hi,
  I've asked yesterday on IRC but so far got no answer. I think it is right to 
file a bug about the current state of systemd autopkgtest to unite the efforts 
in regard to it.

  I was looking at the systemd tests for a no-change rebuild that really
  had no reason to now make it fail. While checking I found that as of
  this month (first bad test on 1st of February) most of the systemd
  test runs on amd64 will not pass/fail but instead in most cases time
  out.

  I've seen various people retry the case as it shows the typical
  symptoms of a "not the fault of the package, let us retry this" case.
  But it seems that won't help as the test history is rather clear.

  We see that formerly we had the known to be somewhat flaky, but
  otherwise working test (time goes from right to left). So we had the
  usual suspects of tests like upstream/systemd-fsck that failed a few
  times, but also working runs in between.

  But since February 22/24 runs failed very bad.
  6 (=B) of those cases are aborting mid execution
    autopkgtest [22:08:58]: ERROR: testbed failure: testbed auxverb failed with 
exit code 255
  And 16 of them timed out
    <VirtSubproc>: failure: Timed out on waiting for ssh connection

  Sadly the 2/24 that didn't hard fail by that where broken by the known
  flaky systemd-fsckd test.

  Something drives this test crazy that we have to find and resolve, at
  the current rate nothing depending on it is likely to migrate.
