查看当前镜像源

less -N /etc/apt/sources.list

可以看到使用的是Debian 默认的源地址 http://deb.debian.org/

备份

没人希望出问题，但是还是要备份

cp /etc/apt/sources.list /etc/apt/sources.list.bak

修改文件

使用vim打开文件

sudo vim /etc/apt/sources.list
# 打开文件后直接输入 ggdG 清空文件
ggdG

将以下代码输入空文件内（下面代码来自清华大学开源软件镜像站：https://mirrors.tuna.tsinghua.edu.cn/help/debian/）
