docker - apt-get update 在以前工作的版本中失败，出现 404

Question

我正在运行 Travis 构建，但在构建 mysql:5.7.27 docker 镜像时失败。 Dockerfile 运行 apt-get update 然后我得到一个错误 W: Failed to fetch http://deb.debian.org/debian/dists/jessie-updates/main/binary- amd64/Packages 404 Not Found.

使用 curl 我可以看到它正在重定向，但重定向到 URL 会导致 404。有没有人看到这种行为并有补救措施？在 debian 进行更改之前，它基本上是无法修复的吗？

Answer 1

这是因为

as Wheezy and Jessie have been integrated into the archive.debian.org structure recently, we are now removing all of Wheezy and all non-LTS architectures of Jessie from the mirror network starting today.

(如您所见 here)

一个解决方案(根据 https://github.com/debuerreotype/docker-debian-artifacts/issues/66#issuecomment-476616579 )是添加这一行:

RUN sed -i '/jessie-updates/d' /etc/apt/sources.list  # Now archived

在使用 debian:jessie 时调用 any apt-get update 之前进入您的 Dockerfile。这将从 sources.list 中删除 jessie-updates 存储库(现在会导致 404)。

因此，虽然以下方法不起作用:

FROM debian:jessie
RUN apt-get update
CMD /bin/sh

它的工作原理是:

FROM debian:jessie
RUN sed -i '/jessie-updates/d' /etc/apt/sources.list  # Now archived
RUN apt-get update
CMD /bin/sh
