Installing NVIDIA drivers on Ubuntu 22.04

I have followed a number of tutorials to install NVIDIA drivers on Ubuntu 22.04, but none has worked so far. Before the update, on Ubuntu 20.04, everything worked fine.

I have tried to install the driver via GUI and console as well. In the console, I have tried to install versions nvidia-driver-525, nvidia-driver-470, and nvidia-driver-515-open by running

sudo apt install [driver version]

I have RTX2080Ti.

If I run sudo ubuntu-drivers autoinstall, I get the following error:

dpkg: warning: version 'unsigned-5.18.10-051810' has bad syntax: version number does not start with digit
dpkg: warning: version 'unsigned-5.18.10-051810' has bad syntax: version number does not start with digit

Any help is highly appreciated.

Assuming this is a fresh install and logged in Ubuntu on Xorg (from settings icon in log in)

do the following:

sudo apt update && apt upgrade -y

just to get any updates, then from this github page https://github.com/lutris/docs/blob/master/InstallingDrivers.md

The following command is what you run to install the nvidia drivers (version 515***; change this to the latest one for your nvidia card; consult the page for more info)

sudo add-apt-repository ppa:graphics-drivers/ppa && sudo dpkg --add-architecture i386 && sudo apt update && sudo apt install -y nvidia-driver-515 libvulkan1 libvulkan1:i386

then reboot with

reboot

Hope this works and check to make sure your OS recognizes your GPU.
