        @Lakshmana just going off of the screenshot I would guess there is a formatting error in

         /etc/sudoers
        

        run

        sudo cat /etc/sudoers
        

        and output what is there.

                  Ubuntu does not use a root user by default.

                    Scott the trouble (as I understand it) is that even the user he created doesn't have root access.

                      Appears to be a corrupt sudoers file, take a look at the following link.

                                  On Ubuntu run.... netstat -tulpn to see if port 22 is listening.

                                      Might need to boot into single user mode and fix /etc/sudoers from there.
