Bug Description

Binary package hint: update-manager

While trying to upgrade from 10.04 to 10.10, update-manager fails with the following error message:

Could not determine the upgrade

An unresolvable problem occurred while calculating the upgrade.

Please report this bug in the 'update-manager' package and try to include the following error message:
'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

As far as I am aware there are no held packages.

This can be a duplicate of bug 614993 (and dozens of 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.

Confirmed: this is indeed a duplicate of bug 614993.

This did not jump out at me when I filed the bug though. Perhaps this is a problem worth fixing?
