Just add the below commanduser@user-linuxhelp:~$
sudo passwd root
[sudo] password for user
: (enter the password of a user that u have currently logged in On Ubuntu 19.04)
New password:
(set the password for root)
Retype new password
: (re-enter the password for root)
passwd: password updated successfully
(Password has been successfully updated )
Now you could use the set password of root to log in to the root account.

It sounds frustrating to encounter that error while trying to switch to the root account! In Ubuntu, you can use sudo to perform tasks requiring root privileges instead of enabling the root password. Check out Pokerogue and Pokerogue Dex for strategies that can help streamline your workflow!
