docker教程如何安装软件包

我只是跟着docker走，我有点迷路了。 我已经在文档中创建了一个mydockerbuild文件夹，并使用教程中的代码创建了一个dockerfile

FROM docker/whalesay:latest
RUN apt-get -y update && apt-get install -y fortunes
CMD /usr/games/fortune -a | cowsay

然后根据教程运行以下命令：

我得到了以下错误：

我认为错误来自apt get update，但当我在计算机上执行此操作时，我没有遇到任何问题。

我正在运行Ubuntu14.04

您可能会尝试根据错误消息调整更新命令：

无法获取某些存档，可能运行apt get update或尝试使用-fix missing

---

所以我发现了问题，错误是容器内的连接问题

对于不使用个人wifi网络的人，我发现了关于这个问题的其他话题

---

因此，我只是在手机上使用3G运行命令，它就可以正常工作。

我的dockerfil中缺少了-fix，现在我的apt get更新没有错误，但安装仍然不起作用，这是另一个问题。不，是同一个问题，教程中的同一个错误
