Debian 10/11更换国内源，解决系统无法更新和软件无法安装问题；同样适用于容器镜像

Debian 默认官方源站节点在境外，导致了更新失败，尤其实在晚上，基本上无法更新，解决这个问题我们只要通过简单的三步更换国内源即可，163网易云、阿里云、清华同方和中国科技大学等源任君选择。

备份现有源

sudo cp /etc/apt/sources.list /etc/apt/sources.list_bak

修改替换国内源

一般情况下，将 /etc/apt/sources.list 文件中 Debian 默认的源地址 http://deb.debian.org/ 替换为国内源即可。

以下国内源选择一个替换即可,个人一般比较喜欢使用阿里的镜像源站。

#中国科技大学
sudo sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
#163网易云
sudo sed -i 's/deb.debian.org/mirrors.163.com/g' /etc/apt/sources.list
#阿里云
sudo sed -i 's/deb.debian.org/mirrors.aliyun.com/g' /etc/apt/sources.list
#清华同方
sudo sed -i 's/deb.debian.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apt/sources.list
