Thanks for your bugreport. Could you please try to run (if you use gnome): $ sudo update-manager -c -d
and see if there is a little button in the update-manager window that says: "Upgrade to 6.10"? Then click on it and follow the instructions. If something goes wrong, please attach the files in /var/log/dist- upgrade/* Thanks, Michael ** Changed in: Ubuntu Importance: Undecided => High Status: Unconfirmed => Needs Info -- Unable to upgrade dapper to edgy - dependency cycle? https://launchpad.net/bugs/62429 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
