By default, for security reasons, Ubuntu disables root login.

If, for some reason, sudo does not do what you want it to, or you would like to directly login as root on a TTY, open a terminal and execute:

sudo passwd root

This will prompt you for your password, then a new root password. As usual, the password will be hidden, without replacement characters. Please try and use sudo as much as possible and only use the above as a last resort, as this is not recommended.
