  An unresolvable problem occurred while calculating the upgrade.

  This was likely caused by: 
  * Unofficial software packages not provided by Ubuntu 
  Please use the tool 'ppa-purge' from the ppa-purge 
  package to remove software from a Launchpad PPA and 
  try the upgrade again. 

  Se nada disso se aplicar, relate esse erro usando o comando 
  'ubuntu-bug ubuntu-release-upgrader-core' no terminal.If you want to 
  investigate this yourself the log files in '/var/log/dist-upgrade' 
  will contain details about the upgrade. Specifically, look at 
  'main.log' and 'apt.log'.
