Ubuntu/Debian换源
有一天，当你打开你Ubuntu/Debian系统的电脑，使用sudo apt updaet && sudo apt upgrade -y命令更新时发现更新速度慢到离谱，而这个慢的原因就是Ubuntu/Debian的软件源仓库在国外。为了解决这个问题，国内有厂商或者学校就把这个Ubuntu/Debian的软件源镜像了过来。国内有很多Ubuntu的镜像源，包括阿里的、网易的，还有很多教育网的源，比如：清华源、中科大源。
我们要做的就是把/etc/apt/sources.list文件中的软件源更改掉。
下载Vim
更改之前让我们先下载一个Vim，如果已有的话可以跳过这一步。
sudo apt update && sudo apt-get install vim -yUbuntu22.04LTS换源
使用sudo vim /etc/apt/sources.list 命令进入编辑界面，按下键盘A键。把原有的源给用#注释掉，在最下面复制以下内容进去。(有清华源、阿里源、中科大源、网易163源，大家自己选一个用就行)
清华源
