  current release.

  Fix Released

Bug description:
  Error message from release upgrade:

  An unresolvable problem occurred while calculating the upgrade.

   This can be caused by:

   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  No pre-release version installed, no unofficial sw.
