Dkms dependency issue

[person1873]

linux-headers for currently installed kernel should be installed automatically as a dependency for all dkms packages, it doesn’t get pulled down with nvidia-dkms

Hi @person1873, and welcome!

I’ve never experienced an issue installing my nvidia’s drivers. How did you install it?

Edit:

And besides, nvidia-dkms already has dkms as dependency for nvidia-dkms:

$ pamac info nvidia-dkms

@Mirdarthos I installed nvidia-dkms using pamac.

sudo pamac install nvidia-dkms

it pulled in the dkms depend, but no linux-header package
as this is a fairly fresh install, there were no headers and i ended up with error output following installation.

seeing it fail this way, I simply installed the headers manually and the dkms triggers compiled the module without issue. just seems a little odd that pamac didn’t even suggest to install kerenel headers at the same time

[Mirdarthos]

That is odd, yes.

Y’know what? I think it’s kind of because for drivers, in particular Nvidia I think, it’s better to use mhwd as per the wiki:

I had done this already, I was installing nvidia-dkms to try and resolve another issue i’m having which i’m about to make another post about.
This just seemed like a bug which i wasn’t too sure where to post

And now I also don’t know.

A very good explanation is given here as to why the linux-headers package for a particular kernel isn’t installed automatically while installing a dkms package:

[root tip] Kernel - Headers - DKMS

What you will learn You will learn why AUR packages tend to create issues when they depend on DKMS and thus specific kernel headers. You will also learn what DKMS is and how to mitigate build issues with DKMS package and other packages depending on the kernel headers. Finally you will learn why the kernel headers is not present by default. What is DKMS DKMS is an acronym for Dynamic Kernel Module Service and is a set of scripts which can update your custom build drivers upon updating your k…

On Manjaro this kernel dependency must be resolved manually - and you need to know which kernel you are using - otherwise pacman defaults to the first header package listed linux414-headers which of course won’t work unless you actually are using 4.14 as the primary kernel.

Thanks for that @ishaan2479

I guess I’ve been a bit spoiled by the debian ecosystem for the last year, which I escaped because of excessive dependency draw down (xorg depending on gnome-session??? wtf ubuntu).
I understand why this is the case for Arch specifically, it makes sense.
seemed like a bug in manjaro due to how easy it’s been to use so far.
but i’m fine with installing my own headers.

cheers for explaining.
