[Bug 806866] Re: 'could not calculate the distribution upgrade' error message pops up whenever I try to upgrade from 10.04LTS to 10.10LTS

[Manfred Hampl]

This can be a duplicate of bug 721306 and 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.
