[Bug 1023732] Re: Ubuntu upgrade from 10.04 to 10.10 fail

[Manfred Hampl]

This might be a duplicate of bug #721306

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 (which most probably will
also remove xserver-xorg-video-all)

and then try the upgrade again.

++++++++++++++++++

If xserver-xorg-video-nouveau blocks the upgrade from 10.04 to 10.10, it
might as well block the LTS upgrade 10.04 to 12.04 with the consequence,
that not (two years later) there might be a higher number of such bug
reports again!
