重新编辑：我想我可能安装了多个版本的 nvidia-driver，其中一些与我的系统不兼容。我遇到了一堆并发症。当我尝试时sudo apt upgrade。我明白了：
The following packages have unmet dependencies:
libnvidia-ifr1-470 : Depends: libnvidia-gl-470 but it is not installed
libnvidia-ifr1-470:i386 : Depends: libnvidia-gl-470:i386 but it is not installed
nvidia-driver-470 : Depends: libnvidia-gl-470 (= 470.161.03-0ubuntu0.18.04.1) but it is not installed
Recommends: libnvidia-gl-470:i386 (= 470.161.03-0ubuntu0.18.04.1)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
于是我按照吩咐做了：sudo apt --fix-broken install
Do you want to continue? [Y/n] Y

我尝试sudo apt autoremove nvidia*
Package 'nvidia-libopencl1-304-updates' is not installed, so not removed
Package 'nvidia-opencl-icd-304' is not installed, so not removed
Package 'nvidia-opencl-icd-304-updates' is not installed, so not removed
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libnvidia-ifr1-470 : Depends: libnvidia-gl-470 but it is not going to be installed
libnvidia-ifr1-470:i386 : Depends: libnvidia-gl-470:i386 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
sudo apt purge nvidia*给出了同样的死胡同。如何解决这些依赖性问题并删除造成问题的多个 nvidia 驱动程序版本？我将不胜感激任何帮助。
我查看了我的“软件和更新”-->“其他软件”，我有一些 PPA，但不知道要删除什么：
