You could try the command "su -" (without the quotes).

By default on friendly Ubuntu type installs root doesn't have a valid password (so all those bots out there hammering on one's ssh door will never get in).
Sorry, I thought the OP had commented that disabling remote root logins over ssh had prevented access, so I assumed that a root password had been set, but it seems that a usermod goof was the more likely cause.
Apologies for my confusion,
