How do I install the correct nvidia drivers on ubuntu?

I was trying to set up nvidia drivers by following this article: when I got the following error:

WARNING:root:_pkg_get_support nvidia-driver-390: package has invalid Support Legacyheader, cannot determine support level
== /sys/devices/pci0000:00/0000:00:03.1/0000:0e:00.0 ==
modalias : pci:v000010DEd00001B80sv00001462sd00003363bc03sc00i00
vendor : NVIDIA Corporation
model : GP104 [GeForce GTX 1080]
driver : nvidia-driver-450-server - distro non-free
driver : nvidia-driver-390 - distro non-free
driver : nvidia-driver-470 - distro non-free
driver : nvidia-driver-510 - distro non-free recommended
driver : nvidia-driver-470-server - distro non-free
driver : nvidia-driver-418-server - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin

I got this error after running the command: ubuntu-drivers devices. I tried to fix it by following the steps in this forum post: Problem installing Nvidia driver on Ubuntu 20.04but after rebooting this error message still pops up.

Should I be concerned, or how do I fix this?
