When I reboot my ubuntu 20.04 focal machine and do a nordvpn connect, I sometimes get this annoying nordvpn error.

Solution 1:

apparently re-installation seems to fix it.

I got this from here

sudo dpkg -P nordvpn
sudo dpkg -P nordvpn-release
cd ~/Downloads 
sudo wget -qnc https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb
sudo dpkg -i ~/Downloads/nordvpn-release_1.0.0_all.deb
sudo apt update 
sudo apt install nordvpn
nordvpn login
nordvpn connect
