Do fresh install debian testing with luks encryption and btrfs as filesystem, then install nix with nix-installer and everything works. After reboot try run program without installation

$ nix run "nixpkgs#neofetch"

Got this error

error: cannot connect to socket at '/nix/var/nix/daemon-socket/socket': Connection refused

Was the Nix daemon started? sudo systemctl status nix-daemon?
