Title:
  unity held back if ubuntu-desktop is not installed during upgrade from
  raring to saucy (upgrade fails)

Status in libunity:
  Fix Released
Status in libunity package in Ubuntu:
  Fix Released
Status in libunity source package in Saucy:
  Fix Released

Bug description:
  [SRU justification]
  Users who have unity installed but not the ubuntu-desktop task will not be able to upgrade using ubuntu-release-upgrader; and those who upgrade using apt will have the unity desktop removed.  We want users to get a correct upgrade from raring to saucy.

  [Test case]
  1. On a minimal installation of Ubuntu Raring install unity (without ubuntu-desktop)
  2. Edit /etc/apt/sources.list to point to saucy.
  3. Run: apt-get dist-upgrade
  4. Observe that unity is marked for removal.
  5. Enable saucy-proposed.
  6. Run: apt-get dist-upgrade
  7. Observe that unity is now marked for upgrade instead of removal.
  8. Run the dist-upgrade tests in jenkins and confirm that they still work.

  [Regression potential]
  Minimal: we are adding an additional Breaks: against a package not shipping in saucy that is meant to be removed on upgrade.  While this could permute apt's upgrade calculation in unexpected ways, this is unlikely.

  ACTUAL RESULT:
  The system cannot upgrade because unity is removed due to the following resolution:
