Linux
In order to remove the application for Linux, type this command in the terminal:
sudo apt-get --purge remove 'nordvpn*'
Alternatively, you can type the following commands:
sudo dpkg -P nordvpn
sudo dpkg -P nordvpn-release
Removing connections that do not use the NordVPN app may require different steps. Typically, you will simply have to remove all the settings you adjusted manually and undo all the changes you made. If you need help, do not hesitate to contact our support team!
