ubuntu修改更新源为163

安装ubuntu后为了使下载及更新软件包更快，需要将自带的源更换为国内的源。以下以163为例：

1.首先备份下原始自带源；

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

2.到http://mirrors.163.com的ubuntu使用帮助文档中，下载相应版本的sources.list, 覆盖/etc/apt/sources.list即可；

使用vim编辑器打开sources.list文件，复制粘贴替换掉刚下载好的sources.list.precise(由于本人使用的是precise-ubuntu 12.04版本的），编辑完后保存退出。

deb http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse

3.更新源

sudo apt-get update
