Title:
  Upgrade from natty to oneiric on amd64 using cdromupgrade fails when
  fetching index files from CD

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  When upgrading from natty to oneiric using the "cdromupgrade" script
  provided in the alternate CD, the following errors are printed:

  W:Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ - Release amd64 (20111011)/dists/oneiric/main/binary-i386/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
  , W:Failed to fetch cdrom://Ubuntu 11.10 _Oneiric Ocelot_ - Release amd64 (20111011)/dists/oneiric/restricted/binary-i386/Packages  Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs
  , E:Some index files failed to download. They have been ignored, or old ones used instead.

  The process then exits.

  This seems related to the multiarch dpkg changes in oneiric.

  Oddly enough, after the first time I got the message, I tried running
  the script again, and it worked fine (I cancelled it later when it was
  downloading packages). On every later re-run, it failed on the same
  error.
