I'm trying to upgrade from Ubuntu Server 11.10 to 12.04 using Update Manager. I figured out that I had to click the arrow next to 'Terminal' and select OK a couple times. Now it's supposed to be "Installing the upgrades" but it's frozen trying to restart mysql for the second time mysql: restarting.... Apache2, atd and cups were all restarted twice after "Restarting services possibly affected by the upgrade". It's been stuck here for nearly an hour.

I read here about killing processes, but I can't get a terminal window to open.

EDIT: I don't know if this matters but there are 6 occurrences in the Distrobution Upgrade window that say:

 debconf: unable to initialize frontend: Gnome
 debconf: (Unable to load Gtk -- is libgtk2-perl installed?)
 debconf: falling back to frontend: Dialog

I should have left the server alone and never run apt-get install ubuntu-desktop yesterday.

I would really appreciate any suggestions.

Thanks,

Mark
