[Bug 1790613] Re: Regression: packagekit crashes updating itself to a new version

[Julian Andres Klode]

** Description changed:

+ [Impact]
  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

+ 
+ [Test case]
+ Upgrade packagekit using pkcon, make sure it does not "crash".
+ 
+ [Regression potential]
+ It could only lead to old packagekitd processes not restarting. packagekit will still be told to restart itself like before, the restart being added was unintended.
