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
