One of the main problems for Windows users as they move to Linux is not knowing some basic commands. For example, in Ubuntu, when you install seteas a password and a user will be set, however this is not the so-called super user (su) or root.
To do some special things and execute some key commands you need root permissions and you do not have the key because it never sets, so by default Ubuntu has no root password to log in as super-user. For this you must go to Applications> Accessories> Terminal and then run the following command:
sudo passwd root
Then it will ask the user password and then the new password for the root, then the confirmation of that key. After that we can access by typing the command as root:
su
That’s it and if they want to leave session super user run the command:
exit
