安装问题
首先开局就是：```Debian读取数据出错 请确认您已经插入了正确的安装介质......```
(我默认的是繁体：```讀取資料時發生了問題 請確認是否已確實放置安裝媒體...```)
处理方法①：推荐！刷入livdCD，安装时候镜像源前用工具ping一下然后看看哪个快
（这个方法不会轻易出现apt更新失败需要手动配置问题以及组件版本过久问题。！不推荐华为镜像源 我装过好几次都缺模块！）
处理方法②：使用ventoy刷入，然后把安装包丢进去。
处理方法③：把电脑吃了(反鸡批剃指纹)
apt配置
终端先备份一下原来的配置，然后再编辑配置修改后Ctrl+X，Y，回车保存即可。
mv /etc/apt/sources.list /etc/apt/sources.list.bak
nano /etc/apt/sources.list
发一下自用的apt配置
