我在Windows 10上使用Docker创建Debian镜像。然而，我认为Docker Desktop，Dockerfile或Docker命令中有问题。
在Docker Desktop中，我对默认配置做了三处修改。
1.在“常规”下，我打开了Expose daemon on tcp://localhost:2375 without TLS。
1.在Resources > Proxies下，我配置了http和https。
1.在WSL集成下，我打开了Ubuntu 18.04。
导致问题的Dockerfile如下：

FROM debian:buster-slim

ENV LANG=C.UTF-8 LC_ALL=C.UTF-8

RUN apt-get update --fix-missing && \
    apt-get install -y wget && \
    apt-get clean

CMD [ "/bin/bash" ]

字符串
如果有帮助，这个替代Dockerfile运行 * 没有问题 *：

FROM debian:buster-slim

ENV LANG=C.UTF-8 LC_ALL=C.UTF-8

RUN apt-get update --fix-missing && \
    apt-get clean

CMD [ "/bin/bash" ]

型
构建Dockerfile时使用的Docker命令如下：

>>> docker build simple-example

型
注意：Dockerfile是simple-example目录中唯一的文件。
在Docker Desktop配置下，尝试使用Docker命令构建Dockerfile会导致以下错误：

这三个- Docker Desktop，Dockerfile或Docker命令-中的哪一个导致了这个错误？我应该做些什么来修复它？
