[errors.ubuntu.com bug bridge]

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

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.

Status changed to 'Confirmed' because the bug affects multiple users.

[Julian Andres Klode (juliank)]

SRUs uploaded for bionic and cosmic. Since we do not use packagekit in gnome-software in xenial, not fixing it there.

Also not fixing it in trusty, as it's close to EOL.

There do not seem to be any more of these crashes, and no regression in terms of new crashes appearing with that version, so it should be good to release.

[Łukasz Zemczak (sil2100)]

Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report.
