the error i get on the client-side of an app, tried ps -ax, nothing interesting, htop doesn't show anything either, user has sudo rights, tried with other users, still get the same error
instelled amnezia with debian installation steps, AmneziaVPN service is running
ps -ax | grep Amnezia

rebooting machine doesn't help, restarting service either
