I have a Nordvpn account, mostly used for some kind of protection when using public WiFi. Its also great to use when you try to be from somewhere else.
But when I tried to install and use it on my laptop with Ubuntu i got an error, basically telling me to try again or contact support.
First I looked in the logs, but not seeing something i easily could fix, and after a reinstall of the application i contacted support. Got a quick response and the fix is doing this:
sudo ln -s /usr/bin/resolvectl /usr/bin/systemd-resolve
Use it in with care, but it helped me 😀
