方案一：

解决方案

1. vi etc/apt/sources.list

2. 将里面的内容替换成下面这些(artful可以更换，主要看http://mirrors.163.com/ubuntu/dists/下面有哪些可用的前缀自行更换)

deb http://mirrors.163.com/ubuntu/ artful main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ artful-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ artful-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ artful-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ artful-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ artful main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ artful-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ artful-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ artful-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ artful-backports main restricted universe multiverse 
之后输入：
sudo apt-get update

方案2：

（1）编辑/etc/apt/sources.list文件
在命令行中输入： sudo vim /etc/apt/sources.list 或者 sudo gedit /etc/apt/sources.list 推荐使用后者
（2）在上面打开的文件开头添加（中科大的源）
