Root password invalid and one bug

[KidKlown (Matt)]

I believe the ‘toor’ root password is only for live boot.
For an install you will need to set the root password yourself.

Auhtentification failure when using su

If you want to use ‘su’ then you need to set the password first. I will say, i recommend just using ‘sudo’ where possible. You should not get into the habit of running su all of the time. But anyway. To set the root / su password, type sudo passwd root, enter your current password, then enter the ‘su’ password you want. You can also remove the ‘su’ password using sudo passwd -d root. Just saying.
