you need to sudo the command first, try this

"sudo su" and the pass should be the one you setup for your user you first installed on system

hope it helps, Ovidiu

You can also do `sudo -s` to gain superuser permissions. Remember, sudo asks for *YOUR* user's password, not a special "root" password.

I don't think it is the same as that bug.

The SU limitation is an imposed restriction, it's a security feature. See for more information.

"By default, the root account is locked in Ubuntu. This means you cannot login as root or use su. Instead, the installer will setup sudo to allow the user that is created during install to run all administrative commands."
