[Bug 1373534] [NEW] Upgrade from 13.10 to 14.04 fails

[Gert]

Public bug reported:

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.
