Build a Weather Station with Elixir and Nerves: 'mix deps.get' does not work if user has not created a keyfile (page 16)

Running mix deps.get in the sensor_hub directory fails with the following error:

** (Mix) No SSH public keys found in ~/.ssh. An ssh authorized key is needed to
log into the Nerves device and update firmware on it using ssh.
See your project's config.exs for this error message.

I expect this is because config/target.exs is looking for a public keyfile (specifically, one of three names), but the text doesn’t talk about needing one or how to create one.

OS: macOS 11.5.2
Fresh checkout of asdf v0.8.0
Fresh installs of erlang 24.0.3 and elixir 1.12.2-otp-24.

Good call out! I’ll be sure to add a note in the book for this issue. All you should have to do it run ssh-keygen and re-create the firmware. For more details take a look at this part of the Nerves documentation: Nerves.Firmware.SSH — nerves_firmware_ssh v0.4.6
