Title:
  17.04 to 17.10 Could not calculate the upgrade

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

Bug description:
  Description:	Ubuntu 17.04
  Release:	17.04

  What i expected to happen:
  Running do-release-upgrade would upgrade from 17.04 to 17.10

  What happend:
  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.

  I have tried to remove all 3rd party packages that i found in /var/log/dist-upgrade/apt.log
  marked as broken.
  I have done "apt autoremove" after removing offending packages.
