Is sudo nixos-rebuild switch --flake github:owner/repo#your-hostname supposed to work with private repos? I just get

error: unable to download 'https://api.github.com/repos/owner/repo/commits/HEAD': HTTP error 404
       response body:
       {
         "message": "Not Found",
         "documentation_url": "https://docs.github.com/rest/commits/commits#get-a-commit",
         "status": "404"
       }

I also tried sudo nixos-rebuild switch --flake git+ssh://git@github.com/owner/repo#your-hostname but here I just get

git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.
...

git push from the directory I'm in works fine.

1. You'll need to use an SSH agent for authentication. Try running ssh-add /path/to/your/key to add your key first, and then give the switch another go.

2. Instead of using sudo straight up, try this command: nixos-rebuild switch --flake git+ssh://git@github.com/owner/repo#your-hostname --use-remote-sudo. It should do the trick.

Just to clarify the use of --use-remote-sudo, this flag is specifically designed to only attempt to gain sudo privileges during the switch phase of nixos-rebuild. By doing this, it allows the build phase to proceed with the permissions of the current user, which is important for accessing the ssh-agent.
