package nvidia-340 (not installed) failed to install/upgrade: trying to overwrite '/lib/udev/rules.d/71-nvidia.rules', which is also in package nvidia-kernel-common-440 440.59-0ubuntu2

[Mauricio Nascimento]

While updating my system running Focal (20.04), my nvidia drivers are not working and now I cannot install the updates (ubuntu-drivers autoinstall).
I tried to purge everything installed and named nvidia and after autoinstalling the correct driver for my system.
Thanks for helping out.

1)
aurion@w540:~$ lsb_release -rd
Description: Ubuntu Focal Fossa (development branch)
Release: 20.04

2)
aurion@w540:~$ apt-cache policy nvidia-340
nvidia-340:
  Installed: (none)
  Candidate: 340.108-0ubuntu2
  Version table:
     340.108-0ubuntu2 500
        500 http://br.archive.ubuntu.com/ubuntu focal/restricted amd64 Packages

3) I would like to be able to install this version of nvidia driver since I have a dockstation and I use the thunderbolt connection for my external monitor

4) I got an error message that the script could not install the drivers. I also had a look into the synaptic additional drivers and the nvidia is selected as installed. However the rendering of my screen is very slow and when I switch to another screen, I can see the window been reloaded.
Also I am unable to connect my external monitor via thunderbolt.
