How to Change an Ubuntu Root Password
Ubuntu is one of the versions of the Linux operating system. By default, Ubuntu does not create a root user. Instead, the computer administrator uses the "sudo" command and his own password to make system changes. You can create a root user, if you prefer. If you have created a root user, you must switch to the root user before changing the root password. If you have not created a root user, your password is the administrator password.
