グーグルは私の友達ではありません、私はこれの原因が何であるかを見つけることができません。これは「apt upgrade」の後に発生するため、最新のパッケージ（pythonなど）をすべて持っています。

Python3

同じYAMLObjectMetaclass構文エラーが発生し、次の環境変数を設定して、gcloud、gsutil、bqをPython 3を使用するように構成することで問題を解決しました：

ENV CLOUDSDK_PYTHON=python3 ENV CLOUDSDK_GSUTIL_PYTHON=python3 ENV CLOUDSDK_BQ_PYTHON=python3

参照： gcloud topic startup

上記の3つの環境変数を設定した後、gcloud sdk 274.0.1-0を正常にインストールできました。

Dockerfileコードブロック：
