Title:
  Cannot upgrade from 13.10 to 14.04

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

Bug description:
  I cannot upgrade from 13.10 to 14.04 and I don't get a clear reason
  why.

  The (dutch) error message from do-release-upgrade:
  Kon de opwaardering niet berekenen 

  Er is een onoplosbaar probleem geconstateerd bij het berekenen van de 
  upgrade. 

  Dit kan veroorzaakt worden door: 
  * Upgraden naar een voorlopige versie van Ubuntu 
  * Gebruiken van de huidige voorlopige versie van Ubuntu 
  * Onofficiële softwarepakketten die niet door Ubuntu geleverd zijn 

  Indien niets van dit alles van toepassing is, meld deze fout dan 
  a.u.b. met behulp van de terminalopdracht 'ubuntu-bug 
  ubuntu-release-upgrader-core'.
