That's the point it is trying to tell you!
In Unix / Linux the root user is unique. There is one and only one root user. All others are mortals, regular users.
No matter what group / passwd file settings / phase of the moon / hurricane it is, no other user can do any task that requires root user's powers.
If you want mortal users to do things which require root priviledges, consider installing and configuring the
sudo package.
This guide will help you configure sudo.
