我知道这个问题在这里已经谈过了：Docker build "Could not resolve 'archive.ubuntu.com'" apt-get fails to install anything
我尝试使用ubuntu：16.04构建一个docker映像，并尝试运行apt-get update，但它会抛出此错误

Err:1 http://archive.ubuntu.com/ubuntu xenial InRelease
  Temporary failure resolving 'archive.ubuntu.com'
Err:2 http://security.ubuntu.com/ubuntu xenial-security InRelease
  Temporary failure resolving 'security.ubuntu.com'
Err:3 http://archive.ubuntu.com/ubuntu xenial-updates InRelease

Err:4 http://archive.ubuntu.com/ubuntu xenial-backports InRelease

我尝试了上面链接中的解决方案，但似乎仍然没有解决我的问题。我创建了包含适当DNS地址的daemon.json，并将其放置在/etc/docker/中，如前所述，并重新启动docker，但仍然没有解决我的问题。我尝试了另一个可接受的答案，即我们将DNS地址添加到/etc/default/docker中，但也没有工作。如果有帮助，我正在通过大学网络上网。
这个问题还有别的解决办法吗？
