Title:
  Upgrade from 13.10 to 14.04 fails

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

Bug description:
  I'm attempting to upgrade from 13.10 to 14.04 (I know I'm late, but I
  could not do it earlier), but it crashes. I disabled all repositories
  and PPAs except for the ubuntu standard repositories. The error says,
  that ubuntu was not able to calculate which system updates are
  available (roughly translated from German). Any help is appreciated a
  lot, I tried a lot and googled the internet for the past week, but was
  not able to find anything helpful.

  The system is up to date using apt-get update and apt-get dist-upgrade

  Probably most relevant output from console:
  Es konnte nicht ermittelt werden, welche Systemaktualisierungen 
  verfügbar sind 

  Ein unlösbares Problem trat beim Berechnen der Aktualisierung auf.

  Dies kann verursacht worden sein duch: 
  * 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. 


  Ein schwerwiegender Fehler ist aufgetreten

  Bitte erstellen Sie einen Fehlerbericht und fügen Sie die Dateien 
  /var/log/dist-upgrade/main.log und /var/log/dist-upgrade/apt.log 
  hinzu. Die Systemaktualisierung wurde abgebrochen. 
  Ihre ursprüngliche sources.list wurde in 
  /etc/apt/sources.list.distUpgrade gesichert.
