Occasionally, I've noticed that the repositories will go down for a spell. I was just trying to update my Karmic Koala (kubuntu 9.10) on my laptop last night and some of the repositories were down. The failure from "archive.ubuntu.org" is no surprise as its supposed to be "us.archive.ubuntu.org. No worries though because if you take a took at your sources.list, its in there both correctly and incorrectly. I just # that section out on mine to avoid that error. It shouldn't have anything to do with the fact that your on a MD now and it worked fine on the core - coincidence. Here's my sources.list:

Your basic issue seems to be that X isn't starting. You should be able to get X going without the upgraded Nvidia drivers. You just won't have VDPAU support (if you card supports it) and you'll want to run UI1.
To get you going, log in as root on the MD (
http://wiki.linuxmce.org/index.php/Logging_In and run:
dpkg-reconfigure xserver-xorg
This should generate a valid enough Xorg.conf to get the A/V Wizard running. To test, from the terminal run:
X
And an x window system should start
Once you are able to get your Nvidia drivers, run:
nvidia-xconfig
That will get you an Xorg.conf with better graphic support. After you have a new Xorg.conf, always re-run your A/V Wizard.
