Could be permissions on install of the OpenVPN Linux client? as it was NOT creating a TUN. So I made one myself (that was the actual issue):
sudo ip tuntap add name tun0 mode tun sudo ip link show If your version of ip does not support tuntap use tunctl as per: https://serverfault.com/a/347900and it connected after asking for VPN Username & Password and finally now have an internet connection.

Alternative solution to try official openvpn3-linux client & installer that should do the config for you: https://github.com/OpenVPN/openvpn3-linux
