Public bug reported:
Binary package hint: update-manager
My upgrade attempt from:
from: Ubuntu 10.04 Lucid
to: Ubuntu 10.10 Maverick
with a: Lenovo ThinkPad T61p
with: nVidia G84M [Quadro FX 570M] (rev a1) graphics card
failed due to a dependency problem of this package:
xserver-xorg-video-nouveau
Workaround
==========
Just four steps:
1. Remove the nouveau package
sudo dpkg -P xserver-xorg-video-nouveau xserver-xorg-video-all
2. Rename xorg.conf file, or Maverick will stay with a blank screen while
booting (!)
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf_lucid
3. Upgrade to Maverick
System=>Administration=>Upgrade Manager
4. After upgrading install the nouveau package again:
sudo apt-get install xserver-xorg-video-nouveau
Background
=========
There is no conflict in Lucid, but there are as soon as the Maverick
repositories are enabled - so the upgrade has to fail.
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
If non of this applies, then please report this bug against the
'update-manager' package and include the files in /var/log/dist-upgrade/ in the
bug report.
Dependency Conflict Backgrounds
=========================
With maverick repositories enabled:
xserver-xorg-video-nouveau depends on xorg-video-abi-8.0 which depends on
xserver-xorg-core (>=2:1.8.99.904) but 2:1.7.6-2ubuntu7.3 is installed
xserver-xorg-core:
Conflicts: xserver-xorg-input-7
Breaks: xserver-xorg-input-synaptics (<=1.2.2-1ubuntu4) but 1.2.2-1ubuntu4 is
to be installed
