[Bug 1790613] Re: Regression: packagekit crashes updating itself to 1.1.9-1ubuntu2.18.04.1

[Julian Andres Klode]

packagekit postinst is restarting packagekit:

deb-systemd-invoke try-restart 'packagekit-offline-update.service'
'packagekit.service'

so yes, that's what's causing the issue. I don't think I agree with the
importance High, though. PackageKit is not normally used for upgrading,
only for installing and removing packages. You have to manually force
this by using pkcon, hence it should be Medium I think.

Title:
  Regression: packagekit crashes updating itself to
  1.1.9-1ubuntu2.18.04.1

Status in packagekit package in Ubuntu:
  Triaged
Status in packagekit source package in Bionic:
  Triaged

Bug description:
  Bionic: 18.04
  Version: 1.1.9-1ubuntu2 upgrading itself to 1.1.9-1ubuntu2.18.04.1

  Updating with pkcon upgrade or plasma-discover crashes packagekit mid
  transaction, requiring user intervention on the command line.

  In plasma-discover the gui reports the crash briefly, but then stalls
  in apparent mid update, requiring the user to force close it and again
  resolve the issue on the command line.

  Example transactions:

  $ pkcon update

  $ sudo apt-get upgrade 
  E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

  and obviously after that doing anything meaningful with packagekit
  like installing a package fails

  $pkcon install kaffeine
