# Use native arm64 containers on M-series Macs. setup-beam auto-picks
# the right Erlang/OTP prebuilt for the container arch; forcing amd64
# emulation (act's default on arm64 hosts) can leave you with binaries
# built for a different arch than the one actually running.

# Pin Ubuntu 20.04: setup-beam's arm64 Erlang/OTP prebuilds on
# builds.hex.pm are ONLY built against Ubuntu 20.04 (libssl1.1) —
# there is no arm64/ubuntu-22.04 variant at the time of writing.
# Using a newer Ubuntu image (22.04/24.04) breaks OTP's :crypto NIF
# with `libcrypto.so.1.1: cannot open shared object file`, which in
# turn breaks `mix local.rebar` (can't make HTTPS requests).
