   ubuntu su -s root Authentication failureIf you got the message like this:
   
   $ su - root
   Password:
   su: Authentication failure
   Sorry.
   
   Then you can input the command:
   sudo passwd root
   open the root user and input the passwd:
   
   $ sudo passwd root
   Enter new UNIX password:
   Retype new UNIX password:
   passwd: password updated successfully
   
   so that you can su -root
   
   Want to close the root user in the ubuntu, run the command:
   sudo passwd root -l
