I'm currently running Ubuntu 7.10 on my Lenovo T61. Whenever I attempt to run an upgrade from either the alternate CD or from the Update Manager, I get the following:

It does not matter which way I attempt doing it--if I go through the update manager it will give me the 'update notes', download the two files, use gksu to prompt me for admin privileges and then it stalls. If I hit the 'update' button from the autorun off of the cd (or, alternatively, try "sh /cdrom/cdromupgrade") it asks me for admin and then gives that same picture again. I left it running for 8 hours last night in the vain hope that it would work.... but it didn't. Any prospective help would be awesome.
