Title:
  could not calculate the upgrade

Status in update-manager package in Ubuntu:
  New

Bug description:
  Couldn't upgrade (to 14.04 from 12.04), got this message which told me
  to report it:

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade.

   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  If none of this applies, then please report this bug using the command
  'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
