详解Ubuntu 16.04 几个国内更新源
如何更改源
1/在修改source.list前，最好先备份一份
执行备份命令
sudocp/etc/apt/sources.list/etc/apt/sources.list.old
2/执行命令打开source.list文件：
可以用vim，gedit,atom等工具打开
sudovim/etc/apt/source.list
或
sudogedit/etc/apt/source.list
或(你得自己安装atom，我觉得挺好的一个工具)
sudoatom/etc/apt/source.list
3/复制源
把下面的任意一下复制到source.list中去，并覆盖原来的文件内容。
