Nvidia Driver Installation Error (sudo apt install nvidia-driver-550)

Please understand my poor English before entering.

My current development environment
ubuntu 22.04
[GeForce RTX 3070 Lite Hash Rate] (rev a1)

I got into trouble installing the Nvidia driver.
I have executed an automatic installation.

qwer@qwer:~$ sudo ubuntu-drivers autoinstall

The results are as follows.

The following packages have unmet dependencies:
linux-modules-nvidia-550-6.8.0-55-generic : Depends: linux-image-6.8.0-55-generic but it is not installable or
linux-image-unsigned-6.8.0-55-generic but it is not installable
Depends: linux-signatures-nvidia-6.8.0-55-generic (= 6.8.0-55.57~22.04.1+1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
There was an error, so the manual installation was carried out.

qwer@qwer:~$ ubuntu-drivers devices

I saw this and did sudo apt install nvidia-driver-550.
After I delete and install the existing graphics driver and reboot, the results are as follows.

NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

The same thing happens when I erase and install the Nvidia driver
The same thing happens when I try to reinstall Ubuntu.

Please tell me the solution.

Following. Seeing the same issue here:

I had the same error this week after allowing a small update to Ubuntu 22.04.
I purged the nvidia drivers and tried to re-install via Software and Updates, Additional Drivers, but no nVidia drivers would install.

I’ve left it running the X.Org.X server driver which seems to run fine. 1440x900 resolution fitted my old HP w2007v screen OK. I use a GForce GTX 750 Ti graphics card.

I got fed up with having to re-install nVidia drivers with every little update anyway.

Why doesn’t Ubuntu work with this well-established kit? It worked on 22.04 before the little update.

It appears this is not a driver problem per se. I have one Xubuntu 24.04 laptop that did upgrade to kernel 6.8.0-55-generic. All my other machines are still on Xubuntu 22.04 and the latest upgrade did NOT advance the kernel version from 6.8.0-52-generic to 6.8.0-55-generic. Hence the version mismatch. Run

uname -r

to check your kernel version and you’ll see. Our grievance is with the kernel package maintainers. Even running

sudo apt update
sudo apt full-upgrade

does not advance 22.04 to the latest kernel.
