How to choose, use and configure a VPN in KDE neon (Guide)

Best VPN Choices for KDE neon

KDE neon is built on an Ubuntu LTS base and uses APT (Advanced Package Tool) to deliver the latest Plasma desktop to enthusiasts and power users. Its technical hallmarks include:

A Debian-style package system (apt, dpkg, .deb files)
Plasma desktop with Qt frameworks and system tray integration
Systemd service management and NetworkManager support
A focus on up-to-date KDE applications rather than frequent distro-level upgrades

With these factors in mind, the ideal VPN clients for KDE neon should:

Provide a native .deb package or APT repository
Offer a Qt-based GUI or seamless CLI for headless setups
Integrate with NetworkManager or offer system tray notifications in Plasma
Support modern protocols (WireGuard, OpenVPN, proprietary as needed)

Here are the top candidates:

ExpressVPN – Polished Qt GUI, .deb package, Lightway protocol
NordVPN – Official APT repo, robust CLI, IKEv2/IPsec amp OpenVPN
ProtonVPN – Strong privacy stance, official Debian repo, WireGuard amp OpenVPN
Mullvad – Anonymous account model, .deb APT repo, Qt GUI amp CLI

Comparison Table

Provider	Package amp Repo	GUI / CLI	Protocols	Key Features
ExpressVPN	.deb APT repo	Qt GUI CLI	OpenVPN, Lightway	Split tunnelling, system tray integration
NordVPN	APT repo	CLI (ncurses)	OpenVPN, IKEv2/IPsec	Onion Over VPN, auto-connect
ProtonVPN	APT repo	CLI (optional GUI)	OpenVPN, WireGuard	Secure Core, NetShield ad-blocker
Mullvad	.deb APT repo	Qt GUI CLI	OpenVPN, WireGuard	Anonymous account, port forwarding

Installing and Configuring on KDE neon

NordVPN

NordVPN’s repository integrates cleanly with APT. Follow these steps to get started:

# Add NordVPN’s GPG key and repository
sudo wget -qnc https://repo.nordvpn.com/gpg/nordvpn_public.asc 
  -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

# Update and install
sudo apt update
sudo apt install nordvpn

# Log in and connect
nordvpn login
nordvpn connect

# Enable auto-connect on boot
sudo systemctl enable nordvpnd
nordvpn set autoconnect on

ProtonVPN

ProtonVPN offers a CLI client via its Debian repository. To install and initialize:

# Install prerequisites
sudo apt update
sudo apt install wget gnupg apt-transport-https

# Add ProtonVPN repo and key
wget -q -O - 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

# Update and install the CLI
sudo apt update
sudo apt install protonvpn-cli

# Initialize and connect
protonvpn init
protonvpn connect

For WireGuard or the optional GUI (protonvpn-cli-gui), ensure the wireguard module is loaded:

sudo modprobe wireguard
sudo apt install protonvpn-cli-gui
mvnpn-gui

Mullvad

Mullvad’s simple anonymous model and Plasma-friendly GUI make it a great match for KDE neon:

# Add Mullvad’s repository and key
echo deb https://repo.mullvad.net/deb/ all main 
   sudo tee /etc/apt/sources.list.d/mullvad.list
wget -qO - https://repo.mullvad.net/gpg/DEB-GPG-KEY-mullvad 
   sudo apt-key add -

# Update and install GUI client
sudo apt update
sudo apt install mullvad-vpn

# Launch the GUI
mullvad-vpn

If you prefer the CLI:

sudo apt install mullvad-vpn-cli
mullvad-vpn login
mullvad-vpn connect

Each of these VPN clients leverages APT for updates, integrates smoothly with KDE neon’s Plasma environment, and offers both graphical and terminal-based controls to suit your workflow.
