如何在 Mac 上修复 Docker 中的“哈希和不匹配”答案

【问题标题】：How to fix 'Hash Sum Mismatch' in Docker on mac如何在 Mac 上修复 Docker 中的“哈希和不匹配”

【问题描述】：

我使用的是 macOS 11.4 和 Docker 3.3.3。我的 docker 文件看起来像

FROM python:3.8.10-slim-buster

RUN apt-get update && apt-get install --no-install-recommends -y \
    # dependencies for building Python packages
    build-essential \
    # psycopg2 dependencies
    libpq-dev

我已经尝试通过Python 使用不同标签的 Docker 映像，并尝试使用 --no-cache 命令创建映像，但是每次我尝试构建映像时，都会收到错误 Hash Sum mismatch

这是我的日志：

非常感谢任何形式的帮助。提前致谢。

【问题讨论】：

我在 ubuntu:16.04 映像上运行时遇到了同样的问题...我什至尝试更改镜像服务器...没有用。本来这个问题不存在的……一定有什么改变了。我能够在较早的构建标记中运行 apt-get update，但在我更新 apt-get 存储库后再次失败......我的 dockerfile 的一部分。

标签： docker ubuntu dockerfile apt-get docker-for-mac

【解决方案1】：

This 回答最终解决了我的问题。即将下面的代码放在RUN apt-get update

之前

RUN rm -rf /var/lib/apt/lists/*
RUN apt-get clean
RUN apt-get update -o Acquire::CompressionTypes::Order::=gz
