Short description of error
Optix rendering does not work. Both viewport rendering and render image using Optix does not work. I get the following error in console:

Exact steps for others to reproduce the error

Basic scene with a cube, a point light and ambient light turned off in world.
Enable Optix in preferences -> system.
Switch to rendered shading mode or render image.

It is not common to see OPTIX problems with GTX 1080ti.
Have you tried upgrading GPU drivers? See https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

450.66 is the best you can get on Debian Buster.

Have you tried the latest development snapshot of blender: https://builder.blender.org/download ?
Many bugs are fixed between the official releases.

OPTIX_ERROR_UNKNOWN does not give us much to go on. There may be an issue in the NVIDIA driver installation, maybe missing OptiX components?

There may also be a clue earlier in the render log, so it would help to post the full output.

Yes, before I filed the report my card was not recognized at all, I found another bug report and based on that installed libnvoptix1 package. Then my card was recognized, but I started getting OPTIX_ERROR_UNKNOWN.

Now I see libnvidia-rtcore is not upgraded, it's still on version 440.100, it could be the issue:

This library is part of the Vulkan real-time ray tracing extensions (VK_NV_raytracing)

It cannot be upgraded since a dependency is not landed on buster-backports for some reason.

Ok, that would be the issue. OptiX depends on rtcore and versions need to match.

This does not seem to be a bug that we can fix in Blender then, but rather something to be fixed in Debian or with your system configuration.
