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