Title:
  uprage 14.04 to 16.04 on 32-bit machine failed

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

Bug description:
  I'm attempring to upgrade from Ubuntu 14.04 to 16.04, after Mattia
  Rizzolo pointed out to me that 16.04 is OK for 32-bit machines.

  The message from Distribution Upggrade was 
  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

  I do use a few non-Ubuntu packages, how can I discover which ones are
  causing the problem, please?

  Cheers, Nevil  (and thanks very much for your support)
