Within the standard ubuntu or the derviertives (kubuntu/edubuntu etc) the root password is not set and the way to gain access to the root commands is via the command line
sudo command here |
I personally prefer to have root password set because then I can use the root admin rights on the desktop without having to constantly type in sudo all of the time, so to set the root password to something that I will use you can use this
sudo set password root |
this will set the password to something that you can remember and thus any time that you want to have a console open as root just type in
su |
and then the password and you are in the root console 🙂
