概要
github actionsをローカル環境で動作確認したい！という理由から、
nektos/act を導入してみた。
どんなworkflowを組みたかったか
github actions のtask内でpythonのスクリプトを実行したい。
ランナーで走らせているUbuntuにpythonをインストールしたい。

ん、 Version 3.9 was not found in the local cache... python v3.9 not found?

対応していないのか？んな、馬鹿な。
解決方法
act -P ubuntu-20.04=catthehacker/ubuntu:act-20.04 push
解説
actのランナーがdockerコンテナイメージ node:16-buster-slim だったらしく、
これが原因でエラーになっていた。
github actions をローカル環境で動作させる時のコンテナイメージを catthehacker/ubuntu:act-20.04 に
変更したらうまくいった。
補足
明示的にコマンドにオプション -P <platform>=<docker-image> を付けて指定しているが、
ここは永続化できる。
$ cat ~/.actrc
-P ubuntu-latest=node:16-buster-slim
-P ubuntu-22.04=node:16-bullseye-slim
-P ubuntu-20.04=node:16-buster-slim
-P ubuntu-18.04=node:16-buster-slim
この部分をエディタで開いて書き換えればOK
