Hello errors.ubuntu.com, or anyone else affected,

Accepted packagekit into bionic-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/packagekit/1.1.9-1ubuntu2.18.04.5
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-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. 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.

Bug description:
  [Impact]
  packagekit (sometimes) crashes when there are errors.

  https://errors.ubuntu.com/problem/1bdc3e539949aa164d276979f62ca0282a54fcbd
  https://errors.ubuntu.com/problem/e9af46c2ad01a15f968379c434fe0bfbf924d034

  [Test case]
  Check that there are no further cases on the error tracker with the proposed version.

  [Regression potential]
  Given that this just changes the return type of a function only used in calls, and the code compiles, there should be no possibility for a regression. Of course, if there were, it'd be segfaults or stuff.

  [Original info]
