It turns out that the root password of ubuntu is randomly generated every time it is started up. How can we get the root permission? Every time sudo is required, it is too troublesome to enter the command sudo passwd, enter the current user password, and then enter the root user password, it is equivalent to creating a password when creating a root user.
