无法安装 nvidia-driver-455（从 450 版本升级）

Question

我有一个基于 Linux Mint 20 Cinnamon Nvidia (GTX 1060) 的系统，当我注意到最新的 Nvidia 驱动程序已经过时，我想立即安装它们。

但是，我似乎无法安装它：

apt-get --dry-run install nvidia-driver-455

抛出以下内容：

我没有任何保留的包裹，也没有任何残留的配置。

目前，我在内核 5.4.0-54-generic 上运行版本 450 没有任何问题。那么，我现在该怎么办？如何调查此事？

问题已解决，由于某种原因，仍然安装了以前安装版本的元包：nvidia-driver-440. 已经在 3 台笔记本电脑上重现，有问题的软件包保持不变，并阻止 Nvidia 更新。

整体更新操作系统后，我重新启动，并发出：

apt-get purge nvidia-driver-440

结果：

The following packages will be REMOVED:
  nvidia-driver-440*
0 upgraded, 0 newly installed, 1 to remove and 1 not upgraded.
After this operation, 19.5 kB disk space will be freed.

Removing nvidia-driver-440 (450.80.02-0ubuntu0.20.04.2) ...

现在上面的试运行似乎没问题。以 root 身份安装：

apt-get --install-recommends install nvidia-driver-455

进展顺利，我的系统现在启动没有任何问题。
