This website is teaching me how to install retroarch. http://ubuntuhandbook.org/index.php/2013/11/install-retroarch-emulator-ppa-ubuntu/ I enter the first line in the terminal, the one that installs the PPA. "add-apt-repository ppa:hunter-kaller/ppa" And in return, I get this: "Error: must run as root" I am quite confused. Help?
All the commands mentioned should be run as root, you can do this by prefixing the commands with
sudo - so you need to run these instead:
sudo add-apt-repository ppa:libretro/stable sudo apt-get update sudo apt-get install retroarch libretro*
