Hi, 
 
	I am brand new to Linux and have tried to follow the quickstart instructions.
 
	I have steam, wine and RCT2 downloaded. I then tried to install Open RCT2 from the PPA but I can't get past the first line...
 
sudo add-apt-repository ppa:openrct2/nightly
	Entering this just gives me the following message "sudo: add-apt-repository: command not found"
 
	Apologies for what I assume is a stupid question. 
 
	Is anyone able to help me, or point in the right direction?
 
	Thanks
