In Ubuntu, the su command for switching to the root permission is switched between users. it can be switched from a common user to a root user, or from a root user to a common user, when a common user switches to the root user, the authentication password is required. In Ubuntu, when a user switches from a common user to a root user for the first time, the system will prompt that the su authentication fails. the solution is as follows: ◆ the process of su to root setting is as follows: test @ test-desktop :~ $ Sudo passwd enter the new UNIX password: re-enter the new UNIX password: passwd: The password test @ test-desktop has been successfully updated :~ $ Su password: www.2cto.com root @ test-desktop:/home/test # If you want to return to a common user from the root user, run the su-*** root @ test-desktop command: /home/test # su-test @ test-desktop :~ $ Author greenboy1
