I did as you suggested.  The output follows:

W: Failed to fetch cdrom://Ubuntu 8.04 _Hardy Heron_ - Release i386
(20080423)/dists/hardy/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 8.04 _Hardy Heron_ - Release i386
(20080423)/dists/hardy/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.
