That's a fair point. I'll look into it.

Hi, I looked into this and it seems that it is indeed using >=
Depends: cuda-libraries-11-8 (>= 11.8.0), cuda-drivers (>= 520.61.05)

Hm no, what you actually have is cuda-libraries-11-8 depends on cuda-drivers and cuda-drivers depends on cuda-drivers-520 = 520.61.05-1 where you have the version number repeated in the name. That is a really bad pattern for things intended to be backward compatible, as multiple installs of cuda will overwrite "cuda-drivers" and each is pegged to a certain "cuda-drivers-X" where X is part of the name. This results in some really weird dependency hells if you try to install more than 1 CUDA version at the same time depending on the order you install them.
$ sudo apt show cuda-drivers
Package: cuda-drivers
Version: 520.61.05-1
Priority: optional
Section: multiverse/devel
Maintainer: cudatools <[email protected]>
Installed-Size: 7,168 B
Depends: cuda-drivers-520 (= 520.61.05-1)
Your 'cuda' packages should use '>=' not '=='
e.g. 'cuda-12' should depend on nvidia>=525 NOT nvidia==525
