You *can* upgrade using a cd, just not using the live disk. You need to get 
the Alternate cd image and when inserted, it should prompt you for the 
upgrade.

this is due to the properties of an Ubuntu livecd, not anything else. The 
Alternate disk iirc has actual packages to install, while the live disk 
basically blasts an image of a system onto disk, and hence has few actual 
packages on it
