bootable cd's can't be upgraded. you have to do an actual install and then make a new .iso of the installation

edit:
never mind. I didn't understand what you were doing. If you are using 8.04 and load a different Ubuntu installation disk, it should ask if you want to add it as a repository and then add it to the software sources. In Synaptic, be sure the software sources include the CD ROM (check the box).

then try,


sudo aptitude dist-upgrade

I've been told that doesn't work any more, but that was how I upgraded and it worked perfectly for me.

If you are trying to upgrade using the alternate cd you can stick the cd in the cdrom and in a terminal type

gksu "sh /cdrom/cdromupgrade"

1.wa.
sudo apt-cdrom -m -d /media/cdrom0 add
