Mount failure after failed ubuntu upgrade.

I've had the desktop computer running non-stop for almost two months now. It's got Ubuntu 10.10 running and I let the updates run every now and then.

Today when I was about to start working on some flex code, I noticed update manager had gone zombie in the middle of upgrading the 'mount' package. I tried stopping it and restarting several times and it failed whatsoever at stage preparing replacement for package mount<blablabla> so I decided it's time to restart the heap of junk for once. When I restarted I got "General error mounting filesystems," and the maintenance shell. After wondering about it a bit I noticed that the mount upgrade had left /bin/mount without the execute bit set and thus the system could not run it.

Luckily I still had the old ubuntu installation on the old hard-disc and for some reason I could successfully run the mount upgrade in a chrooted environment. I think this would amount to complete reinstall to someone less dedicated and would be completely unacceptable for an os. Would be actually nice to know what went wrong with the upgrade all of the sudden.
