docker - 无法在 Windows 上的 Ubuntu 上的 Bash 中从 docker 容器运行 apt-get update

Question

我从 Microsoft Store 安装了 Ubuntu 16.04，并按照此处的说明在 Ubuntu 上安装了 docker 。我能够让 docker 运行，但是当我尝试构建我的 docker 映像时，它在这RUN apt-get update一步失败了。同样，当我使用 运行 Ubuntu 容器时docker run -it ubuntu bash，运行apt-get update会给出以下结果

我尝试清除 apt-cache 并重新生成它，运行apt-get cleanpruning docker 系统，并使用 --allow-unauthenticated但没有任何效果。我从 docker 容器和 ubuntu 运行 df 来检查剩余空间，我的剩余空间超过 20GB，这应该足够了吧？可能是什么问题？
