Comment 13 for bug 727783

I have the same problem on the alternate amd64 iso.

This is after I've spent 3 weekends trying to install an upgrade on my previously broken 10.04.

What a sad state of affaire.

It seems to me that the repository list in apt is still set to look for the CD with that name.

So much more time wasted for such a little issue - testing???

Please update me on how to go forward.
Cheers,
Bob
