Well was your Ubuntu 8.04 CD in your CD-ROM drive?  If not, then
naturally it's not going to find it.  So humor me on this one and put
your Ubuntu CD in the drive and try it again.  If the error goes away,
then you need to edit your /etc/apt/sources.list and either comment out
or remove the references to the CD.  Also you need to go here
http://www.google.com/linuxrepositories/aboutkey.html and download the
signing key and import it to take care of the other error you have
failed to mention in this posting.
