Title:
  I just can't do a release upgrade. No matter what I try.

Status in update-manager package in Ubuntu:
  New

Bug description:
  I'm using ubuntu 12.04 LTS and trying to upgrade to Ubuntu 14.04 LTS.

  I have all upgrades for my current version, but when I try to upgrade
  it returns:

      Checking package manager
      Reading package lists... Done    
      Building dependency tree          
      Reading state information... Done
      Building data structures... Done 

      Calculating the changes

      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. 

  
  So, here I am. I already try to remove all ppa's that I added. And a few other things.

  
  Any advice or response for this bug?

  Thanks in advance
