Ubuntu 更换阿里云软件源（转）

使用Ubuntu 的apt-get来安装软件是总是因为官方源的速度太慢而抓狂。 
但是用阿里云的源就很快，下面总结一下如何更换Ubuntu的软件源。

一、备份

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

二、修改

sudo vim /etc/apt/sources.list

将source.list文件内容替换成下面的

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

三、更新

sudo apt-get update
