Title:
  Upgrade from 14.04 to 14.10 failed

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

Bug description:
  I tried to upgrade from 14.04 to 14.10, but the upgrade failed. I posted the issue on: http://askubuntu.com/questions/571892/troubleshooting-upgrade-to-14-10?noredirect=1#comment788618_571892. They said to post it here as well. 
  I received the message below: 

  Calculating the changes
  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 think it is because I tried to install MATE, but I did not like
  MATE. I uninstalled MATE and after uninstalling MATE, I have had a lot
  of issues. I am not sure about this, it is just a hunch.
