You seem to have two desktop metapackages installed which creates a
difficult situation for the release upgrader.

Please try removing one and then upgrading.

Title:
  Trying to upgrade from 14 to xenial, keeps crashing due to "3rd
  party"?

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

Bug description:
  Multiple attempts to upgrade to xenial on my laptop.  I have a few 3rd
  party software but it's supposed to disable those.  Each time the same
  error occurs.

  lsb_release -rd
  Description: Ubuntu 14.04.5 LTS
  Release: 14.04

  Running from the gui prompt and update-manager -d

  Error:

  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.

  
  This happens at in the Distribution Upgrade program, second step of "setting new software channels", during the "calculating the changes" stage.
