The easy rsa documentation in this guide is outdated and should be updated. Many of the commands after source vars are not available and should be converted to ./easyrsa commands. Even the configuration data in /etc/openvpn/easy-rsa/vars is incorrect / outdated. In its current state, the Ubuntu guide will not work with 18.04. I have been working off 3rd party guides like: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-18-04
