This guide explains how to manually add the ProtonVPN repository to Ubuntu and install the GNOME desktop application.

• Ubuntu with GNOME desktop environment
• Internet connection
• sudo/root access

sudo apt install gnupg
wget -q -O - https://repo.protonvpn.com/debian/public_key.asc | sudo apt-key add -

Note: You may see a warning that `apt-key` is deprecated. This can be ignored for now.

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

sudo apt update

sudo apt install proton-vpn-gnome-desktop

sudo apt install libayatana-appindicator3-1 gir1.2-ayatanaappindicator3-0.1 gnome-shell-extension-appindicator

If the package is still not found:

• Check the contents of the repository file:

    cat /etc/apt/sources.list.d/protonvpn-stable-release.list

  It should contain: 

    deb https://repo.protonvpn.com/debian stable main

• Run:

    sudo apt clean && sudo apt update

If you prefer the command-line interface:

sudo apt install protonvpn-cli

Then log in and connect:

protonvpn-cli login YOUR_USERNAME
protonvpn-cli connect --fastest
