我尝试按照大部分官方指南在 Ubuntu 18.04 上安装 Nvidia 驱动程序以使用 Cuda。但我要使用的某些库需要另一个版本的 Cuda，因此我尝试手动重新安装它。我在安装过程中没有做笔记，所以我不知道到底出了什么问题。
现在，除了驱动程序问题之外，我甚至无法正确更新或重启系统：
在正常模式下，系统无法启动（或者可以启动，但要等很长时间；我等了一个小时，然后关机）。我现在正在以不安全模式加载，但并非所有东西都是这样加载的。例如，第二个屏幕没有连接，亮度没有调整，也没有进入睡眠模式。
如果我尝试通过终端或软件更新程序进行更新，我会收到错误。
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
The following packages have unmet dependencies:
nvidia-cuda-toolkit: Depends: nvidia-profiler (= 9.1.85-3ubuntu1) but 9.1.85-3ubuntu1 is installed
Depends: nvidia-cuda-dev (= 9.1.85-3ubuntu1) but it is not installed
Depends: opencl-dev but it is a virtual package
Depends: libgcc1 (>= 1:3.0) but 1:8.3.0-6ubuntu1~18.04.1 is installed
命令之后 sudo apt 更新 sudo apt 完全升级 错误是：
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
nvidia-cuda-toolkit : Depends: nvidia-cuda-dev (= 9.1.85-3ubuntu1) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
如果我尝试sudo apt--fix-broken 安装我明白了

我也尝试过这样的命令 sudo apt-get clean sudo apt 安装 nvidia-settings sudo apt 自动删除 sudo apt 自动清理 sudo ubuntu-drivers 自动安装
但出现了同样的错误。
我尝试删除错误指向的文件： sudo mv nvidia-cuda-dev_9.1.85-3ubuntu1_amd64.deb /home/sergey/Trash/ sudo mv cublas.h /home/sergey/Trash/
但它并没有什么效果。
我也无法删除 nvidia 模块：
sudo apt-get 删除 --purge '^nvidia-.*'

我的系统是 Ubuntu 18.04.3 LTS。 nvidia-smi 输出 卡信息
我看到其他人也有类似的问题，但他们的解决方案对我来说不起作用。如果能得到任何帮助，我将不胜感激。
UPD：我注意到 CUDA 确实在运行。例如，在 Pytorch 中。
