Title:
  cannot upgrade ubuntu 14.04 to later version

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

Bug description:
  When I try to upgrade 14.04 to a later version via the update-manager
  this fails.

  It tells me that 15.10 would be available, but then claims to try to
  upgrade to 15.04. This fails with the default error message window (=
  this can happen when using a pre-release version etc.). I never used a
  pre-release version.
