我正在运行Travis构建，构建mysql：5.7.27 docker映像时失败。Dockerfile运行apt-get update，然后出现错误W: Failed to fetch http://deb.debian.org/debian/dists/jessie- updates/main/binary-amd64/Packages 404 Not Found。
apt-get update
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，但是重定向到URL的结果为404。有人看到这种行为并且有补救措施吗？在debian进行更改之前，它基本上是不可修复的吗？

这是由于事实
由于Wheezy和Jessie最近已集成到archive.debian.org结构中，因此我们从今天开始从镜像网络中删除Jessie的所有Wheezy和所有非LTS架构。
（如您在这里阅读）
一个解决方案（根据https://github.com/debuerreotype/docker-debian- artifacts/issues/66#issuecomment-476616579）是添加以下行：
RUN sed -i '/jessie-updates/d' /etc/apt/sources.list # Now archived
any apt-get update在使用debian：jessie 进行调用之前，将其放入Dockerfile 。这jessie- updates将从sources.list中删除存储库（现在导致404）。
any apt-get update
jessie- updates
因此，尽管以下操作无效：
FROM debian:jessie RUN apt-get update CMD /bin/sh
它的工作原理如下：
FROM debian:jessie RUN sed -i '/jessie-updates/d' /etc/apt/sources.list # Now archived RUN apt-get update CMD /bin/sh
