Ubuntu 16.04 国内更新源

给自家的Ubuntu下载软件速度有点慢，毕竟是从国外下载软件，就想更换到国内比较好的更新源（就是这些软件所在的服务器），一般直接百度Ubuntu更新源就能出来一大堆，这时候最好是找和自己Ubuntu版本一致的更新源，我的Ubuntu版本是16.04，下面是我找到的一个比较好的更新源

3、编辑新的更新源：

vim /etc/apt/sources.list选择上面其中的一个源写入改文件

4、让更新源生效

sudo apt-get update

5、安装软件

sudo apt-get install 软件名称、例如：sudo apt-get install vim    安装vim
