I didn't realize anybody had ISDN anymore (at least not in the US). DSL

That's because the DVDs are on a different server (or address anyway).
The HTTP URL to what I want is:
The HTTP URL to what you got (but via RSYNC) is
It's MD5 Hash is e8fb95d2f17699f31e660a5e530e2fe5 (if you want to see if
were talking the same thing here with regard to what you downloaded).
I'm thinking that perhaps the cdimage.ubuntu.com server doesn't offer
rsync. I know it's both HTTP and FTP as I've used it both ways before.
Perhaps somebody else reading this has a bright idea. :-)

Well I know for a fact that somebody somewhere on a (K)Ubuntu mailing
list (or web forum) said something like "you should use rsync to update
your CD (DVD?) image. But that's all that was said. The author assumed
the person knew how to do that.
> Yes you will have to rename your file to match what's on the server.
The name is actually the same now. That apparently changed since I
checked a week or so ago.

I did that already. I did it before I tried it previously in case I
botched the rsync and messed up my only copy.
