Title:
  Upgrade not possible

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

Bug description:
  I tryed to upgrade in a Terminal with the command "sudo do-release-upgrade -d"
  and get the following message:

  Änderungen werden berechnet

  Es konnte nicht ermittelt werden, welche Systemaktualisierungen 
  verfügbar sind 

  Ein unlösbares Problem trat beim Ermitteln der Systemaktualisierung 
  auf. 

  Dies kann verursacht worden sein durch: 
  * Aktualisieren auf eine Vorabversion von Ubuntu 
  * Verwendung der aktuellen Vorabversion von Ubuntu 
  * Inoffizielle Softwarepakete, die nicht von Ubuntu bereitgestellt 
  wurden 

  Falls nichts von dem zutrifft, melden Sie diesen Fehler bitte, indem 
  Sie den Befehl »ubuntu-bug ubuntu-release-upgrader-core« in einem 
  Terminal ausführen. 

  
  Ursprünglicher Systemzustand wird wieder hergestellt
