Bug description:
  [Impact]
  Users can't upgrade to next Ubuntu release running the upgrade GUI under Wayland.
  The backport is needed to let Artful users to upgrade to Bionic without applying workarounds manually.

  [Test Case (for update-manager)]
  1. Install 17.10 and all the updates available
  2. Start a wayland session (Ubuntu in GDM)
  3. open a terminal and run the following command:
    $ update-manager -cd
  4. When you're prompted to upgrade to 18.04, accept and proceed.

  Expected result on fixed version:
  Upgrade starts.

  Result on unfixed version:
  The GUI crashes.

  [Regression Potential]
  The upgrade GUI may crash in a different way when applying the workaround fails.
