permissions - Upgraded from 13.10 to 14.04 with wrong user name and can't access any files

I cannot login to the old username because it does not exist on the login screen.
I cannot recreate the old username because I don't have root privileges.

sudo: /usr/lib/sudo/sudoers.so must be only be writable by owner
sudo: fatal error, unable to load plugins
