【Debian 12】解决nvidia-driver的依赖问题的方法
最近我一直在使用Debian 12。像往常一样粗略地执行sudo apt update && sudo apt upgrade时，系统提示找不到nviria-driver的依赖包nvidia-driver-dkms的版本，因此我将写下解决方法。
總結
由于一些软件包被分离出来，似乎需要新增非自由固件仓库记录。

填補
Debian正在讨论从2022年下半年开始在安装程序中是否激活非自由固件（通常是AMD和NVIDIA的GPU驱动程序）。作为结论，他们决定新增非自由固件，与非自由软件分开，将非自由固件移入其中。
作者在本书结尾留下了以下的话。
GNU所說的「自由發行版」與實際效益不相容。就連Minecraft在nouveau上也無法正常運行。這是一個現實中「完全自由」不存在的例子。
