> Ah! I wonder whether it’s because it can’t talk to the running ssh agent, so it can’t unlock the private key…?

Yes, probably this. `System.get_env()` includes `"SSH_AUTH_SOCK" => "/private/tmp/com.apple.launchd.BlahBlah/Listeners"`.

This is _not_ the `SSH_AUTH_SOCK` that my shell’s using – `SSH_AUTH_SOCK=/var/folders/bunch/of/letters/and/numbers/agent.1234`

I’ve got two `ssh-agent` processes running, and Livebook’s talking to the one that doesn’t have my keys loaded.

I wonder how to get `oh-my-zsh` to talk to the launchd-started one, instead of starting a new one…? That’s a problem for a different forum, however.

Thanks for the pointers.
