Hi Antonio, Go to http://hydra.nixos.org/job/nixpkgs/trunk/nixUnstable.x86_64-linux/latest and follow the instructions to download that build result into your store. Then, install it with nix-env -i /full/store/path. Then nixos-rebuild should work (and you can do nix-env -e nix after switching to the new system if you want).
You should ideally run all these steps with the daemon turned back on and NIX_REMOTE set, those are unrelated to this.
