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
