Title:
  UI frozen and no information when the upgrader is installing snap
  packages

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Test Case
  1. Upgrade from Xenial to Bionic with update-manager -d

  Result
  At some point, after the deb packages have been upgraded, the UI freezes completely (cf Screenshot) for several minutes (6 minutes on my test system from a default xenial installation without any snap installed) seemingly doing nothing while the upgrader is installing snap packages.

  It should at least inform the user that snap packages are being
  installed, ideally with the currently running action like for debs.
