Title:
  Release upgrade fails to apply

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

Bug description:
  I received a notification that a new dist release is available. During
  the upgrade process, it fails by telling me that may be caused by ppa
  sources.

  
  ## What I expected to happen

  I expected the upgrade to happen, or to tell me which package fails to
  upgrade/causes dependencies troubles.

  
  ## What happened instead

  The upgrade failed, telling me that may be due to some PPAs and to use
  ppa-purge.

  But my system "has lived", so I'm not sure on how to find the whole
  list of installed PPAs (some have been deleted from apt.sources.d in
  the meantime).
