不同版本ubuntu 换源

ubuntu 换源，自用（把博客园当笔记本了）
因为经常建虚拟机，每次换源需要搜索，记录一下，就不用到处找了。
换源要看你ubuntu版本，不要随便找个教程就完了。
Ubuntu 24.04 之前，源配置文件路径为 /etc/apt/sources.list
从 Ubuntu 24.04 开始，Ubuntu 的软件源配置文件变更为 DEB822 格式，路径为 /etc/apt/sources.list.d/ubuntu.sources

第一步备份，（换源多了懒得备份，没啥用）
第二步 vim 这个文件，删掉原始内容，填充镜像源内容。
不同ubuntu版本的镜像源内容不太一样，最好的方式是去清华源，阿里源等网站找到对应版本的复制下来
啥也不知道可以访问下面链接官方教程，简单易懂
https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
https://developer.aliyun.com/mirror/ubuntu
https://mirrors.ustc.edu.cn/help/ubuntu.html

因为懒得跑各个网站，综合一下

其实好像不同版本不同源只是换了版本名称和网站，但是万一自己改抄错了呢，还是老老实实复制吧。
什么，没有你要的版本？请去上面网站。
什么，没有你还要其他源？我累了，够用了，真的。
累死我了，发布，下线。
