I have installed Ubuntu and it all is ok and until now I have used sudo command. I tried to login as root and to issue su - command but the installation does not recognise my password. I am certain I entered the correct password.... is the sudo password not the same as the root password?

Do have the Linux console installed? If yes, start a session, then you should have a windows with the options on top (Session, Edit, View etc.). Click on Session and then on "new root shell", enter your user password, then enter the following

sudo passwd

Now enter a pasword for the root user (not the same as when you enter sudo somethingelse and then have to enter your user password) twice.

Now open a normal user's Terminal session and try
su

TheNewPassword.
