Ubuntu第三方软件仓库源（国内源）

一般来说ubuntu官方的软件仓库由于服务器在国外，下载更新速度较慢，需要将软件仓库更换为国内镜像点。

1、修改源配置文件

① 先备份原来的配置文件

mv /etc/apt/sources.list /etc/apt/sources.list.bak

vim /etc/apt/sources.list

② 将国内的Ubuntu镜像点添加到配置文件

deb http://mirrors.163.com/ubuntu/ precise main restricteddeb-src http://mirrors.163.com/ubuntu/ precise main restricteddeb http://mirrors.163.com/ubuntu/ precise-updates main restricteddeb-src http://mirrors.163.com/ubuntu/ precise-updates main restricteddeb http://mirrors.163.com/ubuntu/ precise universedeb-src http://mirrors.163.com/ubuntu/ precise universedeb http://mirrors.163.com/ubuntu/ precise-updates universedeb-src http://mirrors.163.com/ubuntu/ precise-updates universedeb http://mirrors.163.com/ubuntu/ precise multiversedeb-src http://mirrors.163.com/ubuntu/ precise multiversedeb http://mirrors.163.com/ubuntu/ precise-updates multiversedeb-src http://mirrors.163.com/ubuntu/ precise-updates multiversedeb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ precise-security main restricteddeb-src http://mirrors.163.com/ubuntu/ precise-security main restricteddeb http://mirrors.163.com/ubuntu/ precise-security universedeb-src http://mirrors.163.com/ubuntu/ precise-security universedeb http://mirrors.163.com/ubuntu/ precise-security multiversedeb-src http://mirrors.163.com/ubuntu/ precise-security multiversedeb http://extras.ubuntu.com/ubuntu precise maindeb-src http://extras.ubuntu.com/ubuntu precise main12345678910111213141516171819202122

2、更新源

apt-get update

现在修改后的国内的ubuntu镜像点就可以使用了。
