From the log:
/etc/ssh/sshd_config: line 65: Bad configuration option: X11UseForwarding

I only happen to know "X11Forwarding" as option, maybe the other one is an old entry or from an outdated howto?

On upgrades the services need to be restarted.
A broken configuration like this will prevent the update to work properly.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
