[Brian Murray]

Hello Christian, or anyone else affected,

Accepted systemd into cosmic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/239-7ubuntu10.5 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-cosmic to verification-done-cosmic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-cosmic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  autopkgtest boot-and-services fails on many architectures very often
  since systemd/239-7ubuntu12

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Bionic:
  New
Status in systemd source package in Cosmic:
  Fix Committed

Bug description:
  [Impact]

   * Boot and services autopkgtest case has become flakey, especially on
  ppc64el but other architectures too.

  [Test Case]

   * Check that boot-and-services passes more reliably

  [Regression Potential]

   * this is a test change only

  [Other Info]
   
   * gdm3 used to start reliably, in nested qemu, with dummy xorg, but it doesn't anymore. Thus stop testing gdm3 coming up as part of the systemd autopkgtest. Mostly, because in realisty it's not that interesting to see if gdm3 works with dummy xorg, as we mostly care about gdm3 working on bare-metal with proper graphics cards intel/amd/nvidia/etc.

  I appreciate that some old known issues on 'upstream' are fixed.
  But looking at the current tests I see that often on amd64 (2/3 and very often on ppc64le (4/4 since ubuntu12 and 11/11 before that version).

  Looking at the list of people hitting retry and the list of packages
  blocked that seems an issue that must be checked.

  See current head of tests at:
  amd64: http://autopkgtest.ubuntu.com/packages/s/systemd/disco/amd64
  ppc64el: http://autopkgtest.ubuntu.com/packages/s/systemd/disco/ppc64el

  One example log:
  https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-disco/disco/ppc64el/s/systemd/20181126_074048_cb8d2@/log.gz

  Example of the error that one can see in the log:
  test_no_failed (__main__.ServicesTest)
  No failed units ... -------- journal for failed service user at 118.service -----------
