Bug Description
on my Attempt to upgrade from trusty gnome desktop version to xenial xerus using the upgrader GUI, it craches on the 2nd step ' setting new software channels' with the 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 ".
