西数超哥博客怎么更换apt源，换源方式 推荐使用163网易的源
一般情况下，这个方法适用于所有的Linux系统，只需要修改/etc/apt/sources.list文件，这里我以Debian系统作为例子给大家演示一下。
方案一、使用sed命令
sed -i "s@http://deb.debian.org@https://mirrors.163.com@g" /etc/apt/sources.list
或者
sed -i 's/security-cdn.debian.org/mirrors.aliyun.com' /etc/apt/sources.list如果使用的https源，则需要执行apt install apt-transport-https，再执行apt update更新源索引
方案二、
这个方案就是直接在sources.list文件里边改
sudo nano /etc/apt/sources.list
或（用哪个编辑器看自己的喜好）
sudo vim /etc/apt/sources.list常用国内apt源地址、
