UPDATE OFF DVD

[mischa falkenburg]

Hello.
Is it possible to "upgrade" an existing Ubuntu installation into an 
Ubuntu Studio installation utilizing a version of Ubuntu Studio that is 
on a DVD (Ubuntu-Studio 8.04.1 i386) ?

I have tried.

When the DVD is loaded into the DVD drive, dvdrecorder opens a file 
browser with the following folders:
dists
doc
install
isolinux
pics
pool
preseed
ubuntu(which looks like a shortcut...there is a curved arrow coming off it)

and:
cdromupgrade
md5sum.txt
README.diskdefines

An icon for Software Updates shows in the upper panel. When that is 
clicked, there is a window which states: "Cannot install all available 
updates"...Some updates require the removal of further software. Use the 
function "Mark All Upgrades" of the package manager "Synaptic" or run 
"sudo apt-get dist-upgrade" in a terminal to update your system completely.

Below this is a list of all the updates that will be skipped.

Closing this reveals a Software Update window: "You can install 290 
updates", clicking OK brings up Downloading package files which is then 
covered by an Information window that says:
"Please insert the disk labeled: Ubuntu-Studio 8.04.1_Hardy Heron_ - 
Release i386 (20080701) in drive /cdrom/"

Clicking OK justs brings up another one, etc.

Placing the DVD in the cdrom drive doesn't read (afaik), and placing it 
in the dvdburner is likewise.

This computer is currently not able to access the Internet so that is 
why I'm trying this install via disk.

Any suggestions?

Thanks-in-advance,
Mischa
