Ubuntu24.04换源方法（新版源更换方式，包含Arm64）

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

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

二、开始换源

1. 备份源配置文件

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

2. 编辑源配置文件

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

通常刚安装的ubuntu24.04系统默认的源配置文件内容如下所示：
