  Calculating the changes

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade: 
  E:Unable to correct problems, you have held broken packages. 

  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 against the 
  'update-manager' package and include the files in 
  /var/log/dist-upgrade/ in the bug report.
