Title:
autopkgtest success rate dropped inhibiting proposed migration
Status in systemd package in Ubuntu:
Fix Released
Status in systemd source package in Bionic:
Fix Released
Status in systemd source package in Focal:
Fix Released
Status in systemd source package in Groovy:
Fix Released
Bug description:
[impact]
autopkgtests are failing/flaky and prevent other packages from
migrating to -updates
[test case]
check autopkgtest history
[regression potential]
in regard to the changed test cases, any regression would likely
result in either an incorrectly passed test, or an incorrectly failed
test.
[scope]
for systemd, this is needed for x, b, and f.
tests in g appear to be mostly stable, but I've opened MR (linked from
this bug) to update the tests there as well.
i don't plan to update x, as it's reaching ESM in ~6 months, and
backporting the test fixes is more work than just a simple code copy,
since there are additional differences/changes needed in the older
version of systemd (and python3). the failing/flaky tests in x have
been like that forever, and people have just retried them; we can keep
retrying them until x moves into ESM next year.
[original description]
Hi,
we had such cases in the past like bug 1817721 for bionic and maybe bug
1892130 is about the same as well. There were more but I didn't want to search
for all of them - what I checked is that there are no open ones clearly
pointing out the recent further drop in already flaky subtests.
In particular the tests "tests-in-lxd" and "systemd-fsckd" were known
to be flaky before, but got even worse.
Here stats of the last 40 runs, it might be a coincidences that this
is after 246-2ubuntu1 landed. Could as well be any other change

(I'm sure LP will make this unreadable, but is is nice in monospace)
Whatever the root cause is - the success rate of these has reduced so
much that the (even formerly questionable) practice of retry-until-
success won't work anymore.
I have run the two tests in a local VM and systemd-fsckd works there
while tests-in-lxd seems to trip over the old flaky fellow being
"boot-and-services".
We had the discussion in the past, but I think I need to again bring
up the suggestion to skip "tests-in-lxd" and "systemd-fsckd" until
they are on reasonable success rates.
