我有一台32位的Ubuntu服务器，运行17.10 Artful＆并安装了docker.io（我的理解是这是唯一适用于32位的版本）
jonny@grizzly ~ $ lsb_release -cs
artful
jonny@grizzly ~ $ apt list | grep docker.io
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
4384:docker.io/artful,now 1.13.1-0ubuntu6 i386 [installed]
我正在尝试使用i386/debian图像（我也尝试过32bit/Ubuntu并获得相似的结果），但是apt-get遇到了问题。来源似乎配置合理，但是apt-get update收到404错误。从浏览器中击中相同的URL（附加.gz）可以正常工作。 ping在Docker映像中工作，wget和curl不可用，因此无法进一步诊断可能的网络问题。
jonny@grizzly ~ $ docker run -it i386/debian /bin/bash

我尝试了在网上找到的各种不同的镜子，没有区别。我还尝试了i386/debian docker映像的一些不同版本/标签。该服务器上没有用于访问Internet的代理。我在这里可能还缺少其他步骤吗？
