How to install AirVPN (Eddie) on Ubuntu, Linux Mint …

… or any Debian-based Linux distribution

In this post we’ll install Eddie, the graphical user interface (GUI) developed by AirVPN. Eddie can be used with any VPN service supporting the OpenVPN protocol, but Eddie is tailored for AirVPN.

Eddie can be downloaded at the AirVPN Linux download page but also has its own website, both them having identical content.

1. Avoid the .deb AirVPN package on Ubuntu / Linux Mint

Installing AirVPN via the official .deb package can cause the following error to happen:

I could reproduce these errors on Ubuntu 20.10 as well as Linux Mint 19.x and 20 “Ulyana”. Trying to launch the AirVPN GUI produces the following error:

Unfortunately, solving the problem is not so easy, as some mentioned dependencies won’t install trouble-free. Installing AirVPN via the PPA repository is much simpler, so that’s what the next paragraph is about.

2. Install AirVPN on Linux using the official repository

Here we will use the commands provided on the official AirVPN Linux download page, NOT the .deb packages. In a terminal, enter the following commands:

wget -qO -|sudo apt-key add -

On Ubuntu, you can safely ignore the following warning:
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
as this instruction seem to be deprecated.

echo "deb stable main" | sudo tee /etc/apt/sources.list.d/

sudo apt update

sudo apt install eddie-ui

The AirVPN GUI is called Eddie and relies on Mono, which may cause a lot of dependencies being installed:

Eddie will automatically install icons in the menus, but can also be started running eddie-ui. Now you’re ready to start using AirVPN – or any other VPN service via OpenVPN.

3. Connect to AirVPN and configure Eddie

Don’t look for AirVPN in the menus but for “Eddie” and an icon with blue clouds. You will to enter the root password upon launch.

Don’t be fooled by the interface design (which may have looked fantastic 15 years ago): you won’t find a more complete VPN GUI on Linux.

1. Avoid the “bootstrap error” and subsequent crashes

If you happen to shut down your internet connection or have configured your router to shut down in the night hours, Eddie will throw hundreds of system notification, an error message (see below) and may become totally unresponsive.
