パスワード：chsh：PAM：認証に失敗しました

走ろうとする

RUN chsh -s /bin/bash www-data 

（dockerfile）/bin/zshに変更してみましたが、まだ機能しません。 Dockerファイルが長すぎます。このファイルには公式リポジトリがあります。https://hub.docker.com/r/alex Cheng/magento2/~/dockerfile/

結果：

  Password: chsh: PAM: Authentication failure
The command '/bin/sh -c chsh -s /bin/bash www-data' returned a non-zero code: 1

それを修正する方法についてのアイデアはありますか？
