从Debian11 bullseye切换到Debian12 bookworm

就在今天Debian发布了新的系统Debain 12-Bookworm，本着折腾的精神把自己的笔记本给做了个升级也尝鲜了一回。下面记录下升级的过程。

替换软件源 在此之前，你最好确保自己的其他软件处于bullseye的最新版本且工作正常。 

sudo apt update && sudo apt upgrade -y

替换软件源

sudo sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list 

更新并升级所有软件包 

sudo apt update && sudo apt full-upgrade 

重启

 sudo reboot

 升级完成后重启你的PC
