Not working with a new version of nerves

[konstantinzolotarev]

Trying to run everything but first it fails on installing deps.

mix deps.get returning:

Dependencies have diverged:
* nerves (https://github.com/nerves-project/nerves.git)
  different specs were given for the nerves app:

  > In apps/kegerator_system_rpi3/mix.exs:
    {:nerves, [env: :prod, git: "https://github.com/nerves-project/nerves.git", override: true, manager: :mix]}

  > In apps/kegerator/mix.exs:
    {:nerves, "~> 0.4.0", [env: :prod, hex: :nerves]}

  Ensure they match or specify one of the above in your deps and set "override: true"
** (Mix) Can't continue due to errors on dependencies

Updated both mix.ex files with last version of nerves {:nerves, github: "nerves-project/nerves", override: true}

After that everything installed.

Execution of NERVES_SYSTEM=rpi3 mix nerves.release.init
Gives:

==> kegerator_system_rpi3
