2404和2204修改镜像的方式不一致

且镜像保存的位置也不一致，位置在/etc/apt/source.list.d/ubuntu.sources

参考：https://blog.csdn.net/Kiffy_Yam/article/details/145876447

1 备份原文件

sudo cp /etc/apt/source.list.d/ubuntu.sources /etc/apt/source.list.d/ubuntu.sources.bak

2 修改文件内容

sudo vim /etc/apt/source.list.d/ubuntu.sources

修改内容为
