At this point, you're going to have to

a) boot from a rescue disk

b) mount the partition on your hard disk that contains /usr

c) chown -R root:root /mnt/tmp/usr (or whatever your path is)

d) chmod 4755 /mnt/tmp/usr/bin/sudo. (I think Ubuntu uses 4755 on
    sudo. CentOS/RHEL use 4111. Either should work.)

e) boot back into your system and test sudo.

After that, you're going to have to find a healthy Ubuntu system and 
figure out if the massive chown you did in step (c) needs to be 
tweaked in various subdirectories of /usr.
