private internet access vpn
This is a payed service (about 40 euro per year).
installation
For now the only way to enable the service to install it again. The service itself is hidden inside the install script. For now that's the way how to start it though if you don;'t want to enable it at boot.
The install guide is on vpn .
Follow the instructions and it's probably best to set it to auto start because it is easier to stop it, (click on the green icon in the taskbar), then to reinstall it every time.
Another option is to start it at boot, but not connect. I presume (i don't want to reboot to test) that you get the lock icon, but it will be red (disconnected).
