I'd recommend uninstalling all NVIDIA driver related packages, rebooting and then following this: https://gist.github.com/Impact123/3...e3#install-nvidia-driversmodules-via-run-file
Note that NVIDIA provides its own apt repo too but support for new Debian releases lags behind too much for me.

Ok, trying to install newest NVIDIA driver, following this guide:

[TUTORIAL] Thread 'NVIDIA drivers instalation Proxmox and CT'

Hi! I post step by step tutorial how to install NVIDIA drivers on Promox server. I hope it will be usefull for someone:

1. Blacklist nouveau:
vi /etc/modprobe.d/blacklist-nouveau.conf

2. Paste, save and quit:
blacklist nouveau
options nouveau modeset=0

3. Update initramfs:
update-initramfs -u

4. Check if nouveau is enabled:
lsmod | grep nouveau

5. Disable nouveau and verify:
rmmod nouveau
lsmod | grep nouveau

6. Ensure GPU is visible:
lspci | grep NVIDIA

7. Download driver (check for most recent version compatible with...

I gave you a up to date documentation on how to install the drivers. Why not follow that?
Can you share apt update?

Because the Nvidia installer gives me error for not finding headers, and the guide Ive used before tells me to install headers

Code:

That looks okay but stick to one guide. My guide (which is stand alone) tells you to run this. What does that return?

Bash:

apt install -y proxmox-default-headers gcc make dkms

meldalinn · Jan 6, 2026

Here you go

Code:

apt install -y proxmox-default-headers gcc make dkms

proxmox-default-headers is already the newest version (2.0.2).
gcc is already the newest version (4:14.2.0-1).
make is already the newest version (4.4.1-2).

As I said, you need to remove all the NVIDIA packages and the DKMS modules first.
Check dpkg -l "*nvidia*" and dkms status. Then apt purge --auto-remove ... and dkms remove ....

meldalinn · Jan 6, 2026

dkms remove worked - but apt purge less so - error same on all 3

Impact · Jan 6, 2026

Once you removed the dkms modules, what does the install command above say now?

meldalinn · Jan 6, 2026

Impact said:
apt install -y proxmox-default-headers gcc make dkms

This one allways worked, but the nvidia installer claims it cant find the headers - however "apt install build-essential pve-headers-$(uname -r)" still doesent work, and NVIDIA still tries to install everytime I do something with apt

Impact · Jan 6, 2026

What I can tell you is that this guide is exactly what I use myself. I can't help you with the other guide s steps. Have you already rebooted?
Is dkms status now empty? What does apt purge nvidia-kernel-dkms nvidia-tesla-535-kernel-dkms say?

meldalinn · Jan 6, 2026

Right, I get that you dont like my guide, but the error from nvidias installer is that it cant find the kernel source tree - and looking up on google, that means the headers, and where they are supposed to be stored, I cant find the ones for my kernel. (6.8.12.10)

Code:

root@proxmox:/usr/src# ls -la
total 43
drwxr-xr-x  5 root root  5 Jan  6 09:36 .
drwxr-xr-x 12 root root 12 Apr  9  2025 ..

drwxr-xr-x  8 root root 14 May 15  2025 nvidia-570.144

Now, the other guide says to install the headers with

Code:

 apt install build-essential pve-headers-$(uname -r)

wich tries to install headers for 6.8.12.10

dkms

Impact · Jan 6, 2026

The kernel you booted needs to match the version that proxmox-default-headers provides. Hence the suggestion to reboot.
First you need to find a way to remove the remnants of the old 570 modules though.

meldalinn · Jan 6, 2026

Progress - found the old installer, and ran it with --uninstall flag

Now the only error on the new install is unable to find kernel source tree - it doesent give an error about a driver already being installed

Still something here - unsure of what this really means, dkms status is now empty

Please forget about pve-headers. This is outdated. The kernel you're currently booted from is not the latest/default one so the header version proxmox-default-headers depends on/installs does not match. Did you pin it? I can't find any pve header packages for 6.8.

meldalinn · Jan 6, 2026

Code:

root@proxmox:~# apt install proxmox-default-headers
proxmox-default-headers is already the newest version (2.0.2).

If that is correct, then I dont understand what Nvidia installer is on about

Impact · Jan 6, 2026

for the currently running kernel

You're running a old kernel so the headers don't match. You didn't answer if you already rebooted or if you pinned this old version.
