debian12修改国内源

提权

如果登录的用户是非root账户的话请输入 su root 然后输入root的密码或直接输入 su然后输入你当前登录账户的密码即可输入密码的时候并不会有任何字符显示

备份当前镜像源

输入一下命令进入镜像源目录，复制一份镜像源并重命名

cd /etc/apt/
cp sources.list sources.list.backup

编辑镜像源文件

使用vim编辑器编辑镜像源文件

vim /etc/apt/sources.list

将文章下方的镜像源站复制并粘贴到镜像源文件中，原有的镜像源可若不想用的话可以直接输入 dd（即按两下D键）删除光标所选的行

当提示 No lines in buffer.(缓冲区中没有行)的时候就说明该文件中已经没有内容啦

当镜像源文件中没有内容了之后就可以按下 I键（下方就会提示 INSERT（插入））

当切换到插入模式的时候就可以将文章下方的镜像源文件粘贴到输入框里面啦（只要选一个镜像站复制粘贴就可以啦）

插入完成之后按下键盘的 esc然后再同时按下 shift和：输入 wq然后按下回车保存并退，出这样镜像源文件就编辑完成啦。

然后更新镜像源和跟系统软件镜像源，如果不想更新系统软件的话不执行第二行的 apt-get upgrade就可以了

apt-get update
apt-get upgrade

那么到此位置镜像源就更新完成啦

小知识~

有没有对镜像源中的 deb和 deb-src的区别有疑惑呀~

deb代表的是包的目录 。

deb-src代表的是源码的目录。

如果不想使用源码镜像源的话可以在 deb-src前使用 #来注释掉该行，比如下方中的代码就是注释掉了 deb-src的镜像源啦
