If you want to define a root password (to use su -): sudo -i, then passwd (or sudo passwd may also work). sudo always asks for the user password.

If your user is in the sudoers group, you can run the "sudo su -" command and then type your own password. If you are not in the sudoers group, You have to type your correct root password after typing the "su -" command. https://docs.fedoraproject.org/quick-...
