E: Unable to locate package nordvpn

Solution 1:

Download the nordvpn-release_1.0.0_all.deb file from the official website. Then install nordvpn-release by running the following command:

sudo apt-get install ./{/path/to/}nordvpn-release_1.0.0_all.deb

After nordvpn-release installs, update your system (make sure to update AND upgrade):

sudo apt update && sudo apt upgrade

You should be able to install nordvpn sucessfully:

sudo apt install nordvpn

Alternatively, you can add the repository and then update your system:

sudo wget -qnc https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb

Then:

sudo apt update && sudo apt upgrade

Finally:

sudo apt install nordvpn

If the issue still persists, manually add the repository to the apt sources list:

cd /etc/apt/sources.list.d/nordvpn.list
sudo nano nordvpn.list

Then add the following lines to the file (ONLY do this if the file is empty or there is text that is commented out):

deb [arch=amd64] http://repo.nordvpn.com/deb/nordvpn/debian stable main
deb [arch=i386 ] http://repo.nordvpn.com/deb/nordvpn/debian stable main 

Then update the system:

sudo apt update && sudo apt upgrade

You should then be able to install nordvpn:

sudo apt install nordvpn

If you get the GPG error of NO_PUBKEY, then copy the following command into terminal:

sudo wget https://repo.nordvpn.com/gpg/nordvpn_public.asc -O - | sudo apt-key add -
