Partly out of interest, and partly because there don’t seem to be any yum packages for Kerbal, I decided to load it on a spare SSD (not using grub, I just go into the BIOS and decide which drive I want to boot). I set up an account. It didn’t ask me to create a password for root, just a personal account. I try to ‘su -i’ and it asks me for a password. I use the one I created for my personal account. Nope.
Way to go, guys.
Ubuntu assumes you will use sudo for everything rooty.
So, “sudo foo” will run “foo” as root, and you use your personal password for sudo.
If you want a root shell, type “sudo su -” in a shell.
Easily fixed. ‘sudo bash’ to get a root shell. Then create a root password.
