我正在尝试在docker镜像中安装一些软件包，但是apt-get命令似乎不起作用......
当我在基于ubuntu：16.04的容器中尝试这个时
apt-get update && apt-get install -y openssh-server
我懂了：

我尝试在这样的Dockerfile中执行此操作
FROM ubuntu:16.04
RUN apt-get update && apt-get -y install openssh-server
CMD bin/bash
并用它构建
sudo docker build -t imagetest .
但我得到了这个：

我搜索了官方文档和一些论坛，但我找到的答案都没有帮助我，而且已经老了......
他们中的一些人说要重新启动docker服务，但它对我不起作用..有些人说使用apt-get update -qq，但它也不起作用......
所以我来这里直接询问并得到最近的回答。
谢谢。
如果apt-get在VM上正常工作，则可以使用网络主机模式构建容器。
docker build --network=host ...
