This now appears to be caused by a failed upgrade leaving a reference to the CD in /etc/apt/sources.list.
My preferred mirror appears to be missing some packages that the upgrade was trying to fetch. This caused a failed upgrade last night. I then switched mirrors and updated/upgraded natty, using update-manager, without looking at /etc/apt/sources.list. When I re-tried the upgrade after that from the same CD, it aborted. I note that after a successful upgrade in a VM,. using the image from daily-20110920.5, term.log starts with warnings about duplicate sources.list entries and after the upgrade, the cdrom entry does indeed have 'main' and 'restricted' duplicated: # added by the release upgrader # deb cdrom:[Ubuntu 11.10 _Oneiric Ocelot_ - Beta amd64 (20110920.5)]/ oneiric main main restricted restricted -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/848659 Title: Upgrade from natty fails with 64-bit oneiric beta cd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/848659/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
