nvidia drivers fail to install BlueBuild #questions

nvidia drivers fail to install

11/27/2025, 1:46 PM

Hello. I'm using the

silverblue-nvidia

base image, which already included nvidia akmods. However, after the last reboot, I get prompted by Gnome Software to enroll MOK for some other NVIDIA drivers. But when I enter my password to do that, I get the error

Failed to call 'kmodgenca'

, because that command is not available on the system.

sounds like something that secureblue has as well, and it's recommended to be ignored:

and btw, *-nvidia base images would be deprecated soon, see they already removed other images other than base, silverblue and kinoite

So I should switch to the main image + the akmods module?

I read this and I'm not sure if it says nvidia images will be deprecated? There's some discussion about it but it seems like no conclusion

I've been around in ublue space, they've agreed on that part but not sure when it will happen. not to mention that copilot pr they have about documenting an integration of nvidia on your own...

you can try using bluebuild's base image instead, they're basically replicating ublue older base images for base, silverblue, kinoite and cosmic https://github.com/blue-build/base-images they'll probably add more systems but not sure about that

We have Nvidia base images. The only thing is, the kernel is not signed by UBlue anymore, it's signed by us. I still have to add a justfile to make enrolling easier

That's what I'm using for now while we get those nice just files from @gmpinder 🙃 Regarding gnome-software, that's a known issue. Fedora added a kmod signing module, which is what you saw there. The ublue people used to build their own version of gnome-software to avoid this, but stopped doing it around v47. Personally, I just remove it from my image and use gnome-firmware + bazaar instead to avoid those messages

oh cool! Is that still experimental? Because the docs still recommend the ublue images

> Fedora added a kmod signing module, which is what you saw there. Why can't ublue/bluebuild use that instead of a custom solution then?

Afaik that plugin is meant to be used in regular fedora, where you install the akmod. That akmod is then used to build the proper rpm and, then, sign it before installing. The problem with that is, if you use it (which you can), it will have to do layer that on top of the base system.

Imho that's one of the drawbacks of this model, that you would need as many images as combinations of kmods like this one. Or let the user build their own images either installing precompiled modules (ublue kmods), or like blue build is doing right now with Nvidia doing the build+install step while the image is being built

Yes, they're expiremental for now

They are based off of what I could gleam from the code in Ublue's main repo and from what I got working for my own personal base images
