warning: Kino.Render.to_livebook/1 defined in application :kino is used by the current application but the current application does not depend on :kino. To fix this, you must do one of:

  1. If :kino is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :kino is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :kino, you may optionally skip this warning by adding [xref: [exclude: [Kino.Render]]] to your "def project" in mix.exs

scrub-otp-release.sh: ERROR: Unexpected executable format for '/Users/guillaume/Workspaces/skyview/_build/_nerves-tmp/rootfs_overlay/srv/erlang/lib/os_mon-2.7.1/priv/bin/cpu_sup'

Got:
 readelf:ARM;0x5000400, Version5 EABI, hard-float ABI

Expecting:
 portable

This file was compiled for the host or a different target and probably
will not work.

Check the following:

1. Are you using a path dependency in your mix deps? If so, run
   'mix clean' in that directory to avoid pulling in any of its
   build products.

2. Did you recently upgrade to Elixir 1.9 or Nerves 1.5?
   Nerves 1.5 adds support for Elixir 1.9 Releases and requires
   you to either add an Elixir 1.9 Release configuration or add
   Distillery as a dependency. Without this, the OTP binaries
   for your build machine will get included incorrectly and cause
   this error. See
   https://hexdocs.pm/nerves/updating-projects.html#updating-from-v1-4-to-v1-5

3. Did you recently upgrade or change your Nerves system? If so,
   try cleaning and rebuilding this project and its deps.

4. Are you building outside of Nerves' mix integration? If so,
   make sure that you've sourced 'nerves-env.sh'.

If you are very sure you know what you are doing, you may place an empty
file in the same directory as the offending file(s) called '.noscrub'.
This will explicitly disable scrubbing for that directory.

If you're still having trouble, please file an issue on Github
at https://github.com/nerves-project/nerves_system_br/issues.
