安装完成Linux之后总少不了要更新软件源， 每次都在命令行里面敲太麻烦了， 于是我写了下面的脚本：

#!/bin/bash

mv /etc/apt/sources.list /etc/apt/sources.list_backup

echo -e "# deb cdrom:[Ubuntu 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.1)]/ xenial main restricted\n

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties\n

deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted\n

deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted\n

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties\n

deb http://mirrors.aliyun.com/ubuntu/ xenial universe\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe\n

deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse\n

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties\n

deb http://archive.canonical.com/ubuntu xenial partner\n

deb-src http://archive.canonical.com/ubuntu xenial partner\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted\n

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe\n

deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse\n" >> /etc/apt/sources.list

apt-get update

apt-get upgrade -y

脚本执行功能如下：

    备份原有的软件源列表文件;  将阿里云换为软件源;  进行更新。

只要使用超级用户执行脚本就好~
