目标
公司容器使用的系统为 Debian，在里面安装软件时特别慢，需要先换源再安装软件最后使用
版本
Debian 12 之后软件源配置文件为 DEB822 格式，路径为 /etc/apt/sources.list.d/debian.sources
之前使用传统的 One-Line-Style，路径为 /etc/apt/sources.list
所以先查看 Debian 版本，以下任意命令均可：
cat /etc/debian_version
cat /etc/issue
cat /etc/os-release
uname -a --这个其实不行，看不出版本来。。。
最后确认系统是 Debian 12.6
换源
因为系统是 Debian 12.6，所以取源中 DEB822 格式的配置，然后写入对应文件即可
