我刚刚按照在线指南在我的计算机上安装了 Ubuntu。
我正在尝试使用以下命令更新我的 Nvidia 驱动程序：
sudo ubuntu-drivers install
不幸的是，这会引发一个错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
nvidia-driver-455 : Depends: nvidia-kernel-source-455 (= 455.38-0ubuntu0.20.04.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我是 Ubuntu 新手，不确定如何解决这个问题，有人有什么见解吗？
