package libnvidia-common-450-server 450.51.06-0ubuntu0.20.04.2 failed to install/upgrade: trying to overwrite '/usr/share/nvidia/nvidia-application-profiles-450.80.02-key-documentation', which is also in package libnvidia-common-450 450.80.02-0ubuntu0.20.04.2

[John McLoughlin]

During sudo apt-get upgrade, there was an error while this package was installing. On restarting my computer, the resolution was set to 800*600 and my gpu (nvidia 1060 6gb) wasn't recognized. Uninstalling the driver and reverting to the nouveu drivers fixed the resolution issue and reinstalling the nvidia-450 drivers via software & updates allowed for everything to go back to normal.

Steps to reproduce: On a machine with an nvidia 1060 6gb, run sudo apt-get update followed by sudo apt-get upgrade, this should result in an error during dpkg. Restart the computer to see the driver issue with display resolution and gpu not labelled correctly.

Steps to resolve for the time being: Uninstall and reinstall nvidia-450 via software & updates, restart computer.

Status changed to 'Confirmed' because the bug affects multiple users.

[Hans Joachim Desserud (hjd)]

The underlying problem is that the file '/usr/share/nvidia/nvidia-application-profiles-450.80.02-key-documentation' is present in both packages, so they run into a conflict when attempting to install both.

[koanvi (koanvi)]

and how to avoid that conflict? remove old driver before install a new one?

Hi I solved it by following this command:
sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450-server
