I was hoping the new xserver-xorg-core package would show up in the maverick repository more quickly, so I could test if that alone resolved my problem, but I got impatient. I ran aptitude purge xserver-xorg- video-dummy , then update-manager -d, and the upgrade was able to proceed. (No word yet on if the remainder of the upgrade works, but it appears that removing xserver-xorg-video-dummy (and earlier xserver- xorg-video-radeonhd ) resolved this particular bug for me.) I hope that information helps.
Thanks for troubleshooting this and finding a resolution, Michael and Jean-Baptiste. -- 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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
