Why These VPNs Shine on ARMA (Omoikane GNU/Linux)

As an IT specialist based in London, I’ve spent countless hours tweaking ARMA (Omoikane GNU/Linux) installations for privacy and security. ARMA is a Debian‐derived distro that uses APT as its package manager, typically running lightweight desktop environments like Xfce, MATE or Enlightenment (E17). Its user base values stability, ease of use and systemd integration. If you’re looking to add a VPN layer without compiling from source or wrestling with dependencies, you need providers offering native .deb packages or official Debian repositories, robust kill-switch support under systemd, and optional GUI front‐ends that integrate smoothly with your chosen DE.

Below, you’ll find the VPNs that best meet those requirements on ARMA, followed by a direct comparison. After that, I’ll walk you through installation and configuration for the top three.

At a Glance: VPN Comparison

1. Mullvad VPN

Mullvad is prized for its stringent no-logs policy, easy Debian packaging and the fact you can pay anonymously. Its GTK-based GUI works well in Xfce and MATE, and you can fall back to the CLI for scripting.

Installation

# Add Mullvad’s Debian repository and install the app
sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg

curl https://mullvad.net/media/gui/deb/mullvad-repo-keyring.gpg 
   gpg --dearmor 
   sudo tee /usr/share/keyrings/mullvad-archive-keyring.gpg >/dev/null

echo deb [signed-by=/usr/share/keyrings/mullvad-archive-keyring.gpg] 
  https://mullvad.net/media/gui/deb stable main 
   sudo tee /etc/apt/sources.list.d/mullvad.list

sudo apt update
sudo apt install mullvad-vpn

Configuration Connect

After installation, start the GUI via your menu (“Mullvad VPN”). To connect via CLI:

# Log in with your account number
mullvad account reconnect

# Check available WireGuard servers
mullvad relay list type wireguard

# Connect to a country (e.g., Sweden)
mullvad connect wireguard se

# To enable the IP leak protection (kill-switch):
mullvad set wireguard killswitch on

# Disconnect
mullvad disconnect

2. ProtonVPN

ProtonVPN’s official support for Debian means you get both a Qt GUI and a polished CLI. It integrates neatly under systemd and supports multihop via its Stealth protocol. Ideal if you want a little more GUI polish in your DE.

Installation

# Fetch and install ProtonVPN’s official Debian package
sudo apt update
sudo apt install -y gnupg curl

curl https://repo.protonvpn.com/debian/public_key.asc 
   sudo apt-key add -

echo deb https://repo.protonvpn.com/debian stable main 
   sudo tee /etc/apt/sources.list.d/protonvpn.list

sudo apt update
sudo apt install protonvpn protonvpn-cli

Configuration Connect

Initialize the CLI and log in:

# Launch interactive setup
protonvpn-cli login

# Follow prompts, then:
protonvpn-cli c --fastest

# Enable the kill-switch
protonvpn-cli ks --on

# To disconnect
protonvpn-cli disconnect

For the GUI, find “ProtonVPN” in your application menu. The Qt client handles server selection, tunnels and kill-switch toggles from within the window.

3. NordVPN

NordVPN’s dedicated Debian package offers the lightweight but powerful nordvpn CLI. If you’re happier in a terminal or need to script connections—say for headless ARMA servers—this is your go-to.

Installation

# Add NordVPN’s repository and install
sudo apt update
sudo apt install -y curl apt-transport-https

curl -fsSL https://repo.nordvpn.com/gpg/nordvpn_public.asc 
   sudo gpg --dearmor -o /usr/share/keyrings/nordvpn-archive-keyring.gpg

echo deb [signed-by=/usr/share/keyrings/nordvpn-archive-keyring.gpg] 
  https://repo.nordvpn.com/deb/nordvpn/debian stable main 
   sudo tee /etc/apt/sources.list.d/nordvpn.list

sudo apt update
sudo apt install nordvpn

Configuration Connect

# Log in
nordvpn login

# Enable kill-switch and auto-connect
nordvpn set killswitch on
nordvpn set autoconnect on

# Connect to the fastest server
nordvpn connect

# Or specify protocol
nordvpn set technology NordLynx

# Disconnect
nordvpn disconnect

Wrapping Up

All three providers—Mullvad, ProtonVPN and NordVPN—offer seamless Debian integration, systemd-friendly kill-switches and clear CLI tooling. If you prefer a GUI in Xfce or MATE, Mullvad and ProtonVPN stand out. If you’re happy with a terminal workflow on ARMA servers or headless setups, NordVPN’s CLI is both robust and scriptable. Pick the one that fits your daily routine, and rest easy knowing you’ve bolted on top-tier privacy to your Omoikane GNU/Linux install.
