在（几乎）无人值守的设置中运行 Ubuntu 20.04 LTS 桌面。该机器配有强大的 NVidia 显卡。我安装了驱动程序sudo ubuntu-drivers autoinstall，一切运行良好。
apt此后没人再跑。
几周后，当机器重新启动时，它仍然停留在黑屏并有闪烁的光标...我必须手动重新运行以下命令才能使其再次工作：
sudo apt -y purge ~nnvidia
sudo ubuntu-drivers autoinstall
如果我看一下/var/log/apt/history.log，就会发现，在 nvidia 驱动程序自发停止工作的时候：

End-Date: 2022-09-02 11:16:13
我猜这unattended-upgrade是原因，但为什么呢？我想禁用unattended-upgrade是唯一的解决方案？
我还在中看到以下内容unattended-upgrades.log：
