1. 1. RunSudo passwd RootAfter the command, the system will prompt you to set a new root account password.
2. 2. ClickSystem-> Administration-> login windowMenu, switch to the security option page, and select the "Allow local system administrator login" option under it.

After performing the preceding two steps, you can use the root account to log on to the Ubuntu system.
