作为一个ubuntu16.04TLS小白，之前从网上学习使用一些安装软件的应用命令，发现怎么也下载不下来。后来从网上找了一些解答，可能是源的问题，ubuntu16.04TLS（以下只写ubuntu，意思就是ubuntu16.04TLS）自带的源是英国的，所以下载东西时自然比较慢，而且有的时候会出现下载不下来的问题。

我后来把源改了一下（改源方法请百度，我是看的这位作者的改源方法，ubuntu的源特别多，我用的是阿里的源），但是改源的时候出现了一下的问题

后来我通过查阅百度和查阅外国网站发现了解决办法，方法如下：

sudo echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

其实就是在一个注册文本中加入了ip 8.8.8.8

改完之后重新更新一下源，用以下命令（切记一定要重新更新源，要不然会出问题！）

sudo apt-get update
