Upgrade from 10.04 to 10.10 crashed

[Engelbert Dandl]

Binary package hint: update-manager

Debug Text: "Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind. An usresolvable problem occurred while claculating the upgrade: E:Fehler: Unterbrechungen hervorgerufen durch pkgProblemResovler::Resolve; dies könnte durch gehlatene Pakete hervorgerufen worden sein. This can be cuased by: * Upgrading to a pre-release version of Ubuntu * Running the current pro-release version of Ubuntu * Unofficial Sofware packages not provided by Ubuntu. Falls nichts davon zutrifft, melden Sie dies bitte als Fehler im Paket >>update-manager<< und fügen Sie die Dateien aus dem Verzeichnis /var/log/dist-upgrade/ Ihrem Fehlerbericht hinzu.

This can be a duplicate of bug 721306 and bug 658458 (and a dozen similar ones)

If the package xserver-xorg-video-nouveau is installed, in several cases the 10.04 to 10.10 upgrade fails with the error message

"Could not determine the upgrade
An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu"

Several persons have reported that after removal of that package the upgrade was successful.

Try this workaround: Open a terminal and enter the command:

sudo apt-get remove xserver-xorg-video-nouveau

and try the upgrade again.
