Title:
  upgrade failing if packages have changed + been removed on the server
  while downloading

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

Bug description:
  Binary package hint: update-manager

  Updating a machine from 9.04 with:

    sudo update-manager -c -d

  results in update-manager downloading several hundred megabytes and
  then erroring out on the last four files:

    ...

  My guess is that the published packages have been bumped in the mean
  time (manually looking in the FTP directory shows that '-15.52' is
  available, published earlier today.
