[Bug 1903724] Re: [SRU] Package fails to build with missing 'systemctl'

[Brian Murray]

Hello Chris, or anyone else affected,

Accepted nova into focal-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/nova/2:21.1.0-0ubuntu2
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, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

** Changed in: nova (Ubuntu Focal)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-focal

Title:
  [SRU] Package fails to build with missing 'systemctl'

Status in nova package in Ubuntu:
  Invalid
Status in nova source package in Focal:
  Fix Committed

Bug description:
  [Impact]

  Artful (OpenStack Train) through Focal (OpenStack Ussuri), the Nova
  package now fails to build with unit tests failing because they're
  missing the `systemctl` binary. An example traceback from the tests is
  included in the Other Info at the end.

  This affects the ability to backport fixes or upstream point releases
  to the Nova package in Ubuntu.

  [Test Case]

  Reproducing this error is doable by building the package:

  git clone lp:~ubuntu-openstack-dev/ubuntu/+source/nova
  cd nova
  git checkout stable/ussuri
  gbp buildpackage -S -sa
  pbuilder-dist focal build ../build-area/nova_*dsc

  [Where problems could occur]

  This upload doesn't change anything in the deployed software, merely
  in the build environment. With that caveat, building on an environment
  that cannot install systemctl could continue to leave this package
  unbuildable.

  [Other Info]

  Below is an example of one of the unit test failures that is resolved
  by adding systemctl as a build dependency.
