[ubuntu-za] Using a CD as the sole repository

[Phillip Pare]

When I try and update the package list from an Ubuntu 8.04 CD alone 
without using the online repositories get the following messages. This 
is even after I have used synaptic to made the CD-ROM recognizeable by APT.

Failed to fetch cdrom:[Ubuntu 8.04 _Hardy Heron_ - Release i386 
(20080423)]/dists/hardy/main/binary-i386/Packages.gz  Please use 
apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot 
be used to add new CD-ROMs

be used to add new CD-ROMs
Some index files failed to download, they have been ignored, or old ones 
used instead.

When I tree and use sudo apt-cdrom add from the command line I still get 
an error:
phillip at phillip-desktop:~$ sudo apt-cdrom add

My fstab file is as follows:
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0

# /dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8

I did check the integrity of the disk from the opening menu and there 
was not a problem.

Does anybody have any suggestions as to how I should now proceed?

Thank you.
