dialout グループについて
dialout: Full and direct access to serial ports. Members of this group can reconfigure the modem, dial anywhere, etc.
cli がなさそうなので、snap でなく apt 経由
$ snap install arduino --channel=latest/edge
apt にも cli なさそうなので、homebrew (linuxbrew) 経由かマニュアルインストール
$ brew update
$ brew install arduino-cli
scratch
$ sudo snap install s4a
