Ubuntu24.04换源方法（新版源更换方式）

yycvip

一、源文件位置
Ubuntu24.04的源地址配置文件发生改变，不再使用以前的sources.list文件，升级24.04之后，而是使用如下文件

1. /etc/apt/sources.list.d/ubuntu.sources

复制代码

二、开始换源
1. 备份源配置文件

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

复制代码

2. 编辑源配置文件

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

复制代码
