[Bug 1710383] Re: Could not install 'gconf2' and upgrade frozen

[Peter Valdemar Mørch]

I've just seen this in a 16.10 -> 17.10 upgrade too. I hit enter i think
about 100 times. Eventually the dialog stayed closed.

The upgrade later came with a similar dialog box saying: "Could not
install linux-image-4.13.0-39-generic", later similar for "linux-
firmware"

In the end it reported: "Could not install the upgrades"/"The upgrade
has aborted. Your system could be in an unstable state. A recovery will
run now (dpkg-configure -a)". And later: "Upgrade complete"/"The upgrade
has completed but there were errors during the upgrade process."

I have a VirtualBox virtual machine snapshot from which this occurred,
so I believe this is reproducible from here. I'd be happy to hand it
over to a developer if someone wants to have a look at what is
occurring. I promise to keep it around two weeks, so until May 20, 2018

Bug description:
  When performing a distribution upgrade from Ubuntu 16.04.3 xenial to

  The dialog has a Close button. Clicking it closes the dialog but it
  then reappears again immediately. It is stuck in a loop.

  The distribution upgrade dialog continues in the background for a
  while. However, it then freeze having last reported "Configuring
