Sudo su root # passwd

Use the command: sudo passwd root

The second kind: when the user does not have sudo permission

Restart the lunix system and press Shift during startup to enter GRUB map mode

Select the Ubuntu Advanced option and press Enter to enter the environment

Then press the e key to enter the recovery mode to enter the startup parameters, press the page down to see the penultimate line of recovery nomodeset to delete
