apt get在基于Debian和Ubuntu的docker映像中失败

在Debian或Ubuntu docker映像中运行apt get update时，我遇到了一个奇怪的错误：

我检查过，URL不存在，应该是.gz或.bz2。它只发生在一台主机服务器上（运行Ubuntu），目前在boot2docker和Debian中运行良好。

我发现这是由于我们在服务器上设置了IP表规则，该规则将端口80重定向到本地主机端口5000。它是在两个方向上意外设置的

apt get正在请求不带.gz/.bz2的URL，因为它已经失败了。

错误是因为您的实例存在网络问题。最可能是缓存代理或坏镜像。解决此问题的最简单方法是使用VPN连接从其他地理位置获取更新包，这将触发不同的镜像
