[Bug 1388511] Re: "Could not calculate the upgrade. "12.04 ->14.04- openmpi dependency issue

[Eric]

People say that ROS is the issue, so I am removing it now, and if you didn’t know, you have to type
"sudo apt-get remove ros-*"
OR
"sudo apt-get purge ros-*"

Title:
  "Could not calculate the upgrade. "12.04 ->14.04- openmpi dependency
  issue

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed
Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  Could not calculate the upgrade. An unresolvable problem occured while
  calculating the upgrade". There are no details in the error dialog
  about what went wrong. A screenshot of the error dialog and the usual
  Ubuntu-collected information is attached.

  This is a dupilcate, of course, but the bug reporting system won't
  find the correct bug report (Bug #1274672 ) even if the exact title or
  number is given.  A Google search indicates 1,100 hits related to
  "could not calculate the upgrade". So it's probably a real bug.

  Some comments on this bug indicate that "cinnamon" is the problem.
  "Cinnamon" is not installed.
