Systemctl not recognizing openvpn service file.
I am attempting to setup a VPN server on Ubuntu 16.04 using a Droplet. I followed this tutorial "https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-16-04" here. I did everything exactly as given, however when I tried to use sytemctl to start openvpn, I found out systemd is not installed and server is running with Upstart. Since I am not too familiar with this, I downloaded systemd for Ubuntu 16.04. However, now running $ systemctl start openvpn@servername gives me the error that no such file is found. Running $ systemctl status openvpn gives me the same error in the Loaded section. I check /lib/systemd/system/ and no openvpn service file exists. How can I get sytemctl to recognize openvpn?
