Ubuntu 快速更换 AliSource

​

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。

​

镜像下载、域名解析、时间同步请点击 阿里巴巴开源镜像站

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：可以通过阿里云开源镜像站资源目录查看是否支持当前系统的Codename。
