I am trying to follow this guide https://airvpn.org/linux/ but having trouble on a Ubuntu 13.10 machine. I don't even know if I should be using the AirVPN instructions (top) or the Ubuntu Network Manager instructions (bottom). Anybody willing to help me step by step. I'm pretty good at following instrucitons but terminal commands are challenging for me. I need help to know what the exact terminal command is. Anybody willing to help me with the first step? Should I be trying to do this with AirVPN or the Ubuntu Network Manager?
