Thank you, I added the missing md5sum in our repository.  What grieves
me more is that I don't know why the preinst script didn't completely
fail, the relevant lines of code are

get_sarge_md5sum_from_list(){
  file=$1
  set $sarge_md5sum_list
  while [ $# -gt 0 ]; do
    if [ $file = $1 ]; then
      echo $2
      return 0
    else
      shift 2
    fi
  done
  echo "$file: md5sum not known. Exiting" >&2
  return 1
}

If a function in a set -e script returns one, why doesn't the script
fail?  Or did dpkg silently try new-preinst failed-upgrade and was happy
with its exiting cleanly?

Regards, Frank
