转载：Ubuntu 快速更换阿里源-阿里云开发者社区 (aliyun.com)

简介： 本文主要给大家讲解如何为Ubuntu更换阿里源，通过以下四个步骤即可快速实现换源。

一、查看ubuntu的Codename

lsb_release -a | grep Codename | awk '{print $2}' # 输出结果为下文中的Codename

 

二、备份系统源

cd /etc/apt

sudo mv sources.list sources.list.bak

 三、写入阿里云的源

vi sources.list

 下面源信息中$Codename为第一步中系统的Codename，用记事本批量替换即可。

deb http://mirrors.aliyun.com/ubuntu/ $Codename main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ $Codename-backports main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ $Codename-proposed main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ $Codename-security main multiverse restricted universe

deb http://mirrors.aliyun.com/ubuntu/ $Codename-updates main multiverse restricted universe

deb-src http://mirrors.aliyun.com/ubuntu/ $Codename main multiverse restricted universe

deb-src http://mirrors.aliyun.com/ubuntu/ $Codename-backports main multiverse restricted universe

deb-src http://mirrors.aliyun.com/ubuntu/ $Codename-proposed main multiverse restricted universe

deb-src http://mirrors.aliyun.com/ubuntu/ $Codename-security main multiverse restricted universe

deb-src http://mirrors.aliyun.com/ubuntu/ $Codename-updates main multiverse restricted universe

四、执行更新

执行以下命令，完成更新。

apt-get update

说明：可以通过ubuntu-dists安装包下载_开源镜像站-阿里云查看是否支持当前系统的Codename。
