Install easy-openvpn

To install the latest stable release of easy-openvpn from the Ubuntu store:

 $ snap install easy-openvpn

All necessary plugs and slots will be automatically connected upon installation, except the home plug. You can verify this with:

$ snap interfaces
Slot                       Plug
:network                   easy-openvpn
:network-bind              easy-openvpn
:firewall-control          easy-openvpn
:network-control           easy-openvpn

You probably need to connect the home plug manually if you copy the client ovpn file to your home directory and connect the client to server with it.

$ snap connect easy-openvpn:home :home
