1.查看debian的发行版本信息
cat /etc/os-release
2.更换apt-get的源：
修改源配置：
vim /etc/apt/sources.list
根据debian的版本在配置中加入合适的阿里源（也可选择其他源）：

deb http://mirrors.ustc.edu.cn/debian buster-backports main contrib non-free
deb http://mirrors.ustc.edu.cn/debian buster-proposed-updates main contrib non-free
deb http://mirrors.ustc.edu.cn/debian-security buster/updates main contrib non-free
cat <<EOF > /etc/apt/sources.list
deb http://mirrors.aliyun.com/debian/ buster main non-free contrib
deb http://mirrors.aliyun.com/debian/ buster-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ buster-backports main non-free contrib
