I am having the same problem trying to upgrade. Tried removing the xserver-xorg-video-nouveau package as people were suggesting and this did not help me! I had a completely up to date system, and even when in unchecked all my third party package sources in my package sources before attempting this time.
This bug is not fixed. For now I am stuck. ** Attachment added: "Main.log from attempted upgrade." https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/614993/+attachment/1718186/+files/main.log -- 10.04 -> 10.10 upgrade fails: pkgProblemResolver::Resolve generated breaks: xserver-xorg-video-v4l demoted to universe https://bugs.launchpad.net/bugs/614993 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
