1、復制原文件備份

sudo cp /etc/apt/source.list /etc/apt/source.list.bak

2、編輯源列表文件

sudo vim /etc/apt/source.list

3、將原來的列表刪除，添加如下內容

deb http://mirrors.aliyun.com/ubuntu/ vivid main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ vivid-updates main restricted universe multiverse

4、運行sudo apt-get update

5、運行sudo apt-get upgrade

修改Ubuntu的aptget源為阿裏源的方法
