我的sources.list文件看起来像这样（官方示例来自Debian 维基）：
deb http://deb.debian.org/debian stretch main
deb-src http://deb.debian.org/debian stretch main
deb http://deb.debian.org/debian stretch-updates main
deb-src http://deb.debian.org/debian stretch-updates main
deb http://security.debian.org stretch/updates main
deb-src http://security.debian.org stretch/updates main
我也尝试过其他版本，但遇到了同样的错误。有谁知道可能导致问题的原因吗？非常感谢！
编辑：
谢谢优雅重启，我之前通过在Dockerfile中手动设置Debian镜像的网络代理最终解决了这个问题apt update。
虽然问题被标记为重复，但与Debian：存储库没有发布文件，因为这是 400 错误，而sources.list文件实际上是正确的。
答案1
Debian 9 源码.list Debian 测试的sources.list 与Debian 9（代号Stretch）不兼容
下面是一个 source.list 示例：
deb http://ftp.us.debian.org/debian/ 拉伸主要贡献非免费 deb http://ftp.us.debian.org/debian/stretch-updates 主要贡献非免费 deb http://security.debian.org/debian-security/stretch/updates 主要贡献非免费
以下sources.list尝试使用重定向来提供靠近您的位置的内容：
deb http://deb.debian.org/debian/ 拉伸主要贡献非免费 deb http://deb.debian.org/debian/stretch-updates 主要贡献非免费 deb http://deb.debian.org/debian-security/stretch/updates 主要贡献非免费
要更新您的系统，请照常进行：
apt-get update # 从源更新包信息 apt-get update # 升级包 apt-get dist-upgrade # 升级依赖于新依赖项的包
我确实建议在预生产环境中进行测试后，手动进行安全更新，或者将其作为计划升级的一部分通过其他配置系统进行。或者，您也可以安装无人值守升级包。
