sudo update-manager -d -c does not upgrade to latest version 8.04

Thanks for your bugreport.

What version of update-manager do you currently run on gutsy? Could you please check that you got the latest one from gutsy-updates?

If one of your other computers failed to upgrade (and now boots into busybox), could you please include the logs in /var/log/dist-upgrade of the failure in a new bugreport? That would help us diagnose the issue?

Thanks,
 Michael

This is the computer that boot in BusyBox:

The other computer is now in the process of a Distribution Upgrade, so I think that problem went away or worked around when I did a terminal:
sudo update-manager -d without the -c. I had tried that before but then it didn't work later. thank, so you can probably close that part of the bug.

I'm going to go ahead and close this as the original issue has been taken care of and the second issue is now found in Bug #192796.
