The PIA installation tutorial is excellent, although it focuses only on Ubuntu for installing the standard Linux client. I won’t detail the installation process here, as there wouldn’t be any added value compared to the “official” tutorial.
There are only a few things left to say about installing PIA VPN on Linux:
Eddie, the AirVPN visual interface, is based on Mono and sometimes feels unresponsive. Eddie is subject to random crashes, although they do not happen very often:
Even if the AirVPN GUI crashes, active OpenVPN connections will not be interrupted.
“No latency” used to be a good thing
Another common problem with Eddie is the disappearance of the “latency” values from the servers list – for no apparent reason. Active OpenVPN connections will stay alive, but connecting to a different VPN server without latency information makes no sense.
After disconnecting and restarting Eddie, the “latency” column will reappear – but restarting Eddie will interrupt the current connection.
AirVPN on Linux pros & cons
Most complete graphical user interface on Linux (Eddie)
Whitelisting and blacklisting of countries and servers
Eddie and Hummingbird are open source software released under GPLv3
Sluggish and crash-prone GUI
Outdated UI design, no HiDPI support
No WireGuard support
AirVPN has a many options that no other VPN offers on Linux, for example whitelisting / blacklisting entire countries or specific servers, a “Network Lock” (kill switch) based on firewall rules, Tor integration and a home-brew OpenVPN version 3.
AirVPN’s visual interface for Linux (Eddie) offers more options than any other VPN GUI on this platform. Despite being a bit unstable and antiquated, Eddie is probably one of the best options for Linux users in 2021.
