Ubuntu 快速更换阿里源
转载:Ubuntu 快速更换阿里源-阿里云开发者社区 (aliyun.com)简介: 本文紧张给各人讲解如何为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 $2}' # 输出结果为下文中的Codename https://img-blog.csdnimg.cn/direct/40191463c39249798888ac8a3416e0f8.png
二、备份系统源
cd /etc/apt
sudo mv sources.list sources.list.bak 三、写入阿里云的源
vi sources.list 下面源信息中$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
