That's expected by `build-remote` and makes sure that errors are correctly forwarded to the user. For instance, let's say that the host-key of `example.org` is unknown and nix-build ../nixpkgs -A hello -j0 --builders 'ssh-ng://example.org' is issued, then you get the following output: cannot build on 'ssh-ng://example.org?&': error: failed to start SSH connection to 'example.org' Failed to find a machine for remote build! derivation: yh46gakxq3kchrbihwxvpn5bmadcw90b-hello-2.12.1.drv required (system, features): (x86_64-linux, []) 2 available machines: [...] The relevant information (`Host key verification failed`) ends up in the daemon's log, but that's not very obvious considering that the daemon isn't very chatty normally. This can be fixed - the same way as its done for legacy-ssh - by passing fd 4 to the SSH wrapper. Now you'd get the following error: cannot build on 'ssh-ng://example.org': error: failed to start SSH connection to 'example.org': Host key verification failed. Failed to find a machine for remote build! [...] ...and now it's clear what's wrong. Please note that this is won't end up in the derivation's log.
