Issue installing facetimehd DKMS module on kernel 6.15.9-arch1-1

Hi everyone,
I'm experiencing an issue when installing the facetimehd DKMS module on Arch Linux, running kernel 6.15.9-arch1-1.
During the DKMS install step, I get the following error:

(10/20) Install DKMS modules
==> dkms install --no-depmod bcwc-pcie/0.6.13.r0.g4990044 -k 6.15.9-arch1-1
Deprecated feature: CLEAN (/usr/src/bcwc-pcie-0.6.13.r0.g4990044/dkms.conf)
Deprecated feature: MODULES_CONF (/usr/src/bcwc-pcie-0.6.13.r0.g4990044/dkms.conf)
==> dkms install --no-depmod facetimehd/0.6.8 -k 6.15.9-arch1-1
Deprecated feature: CLEAN (/usr/src/facetimehd-0.6.8/dkms.conf)
Deprecated feature: MODULES_CONF (/usr/src/facetimehd-0.6.8/dkms.conf)
Module /usr/lib/modules/6.15.9-arch1-1/updates/dkms/facetimehd.ko.zst already installed (unversioned module), override by specifying --force

Error! Installation aborted.
==> WARNING: `dkms install --no-depmod facetimehd/0.6.8 -k 6.15.9-arch1-1' exited 6

The bcwc-pcie module installs without fatal errors (just deprecated warnings), but facetimehd fails with exit code 6. This prevents me from completing the update process properly.
What I've tried:
    Uninstalling and reinstalling the facetimehd and bcwc-pcie DKMS modules.
    Manually removing /usr/lib/modules/6.15.9-arch1-1/updates/dkms/facetimehd.ko.zst.
    Running dkms remove and dkms install manually.
    Updating my DKMS and kernel headers to the latest versions.
    Trying with --force results in the same issue later during the boot process.

My system:
    MacBook Pro 2015
    Arch Linux (latest updates)
    Kernel: 6.15.9-arch1-1
    Using systemd-boot
    Only Hyprland installed (Wayland session)
    Wired internet during setup
    DKMS is version: 3.0.12 (from dkms package)

Any ideas on how to resolve this? Is this related to the deprecated fields in dkms.conf, or is it something else? Would it be safe to force the install, or could that lead to other issues?

Thanks in advance

I'm not sure I see the problem here. It fails because it was already built, so it should be fine, right? What, exactly, were you doing when you got this error? It shouldn't stop you from completing anything, and I have NO idea how you could run into this at boot.

Re: Issue installing facetimehd DKMS module on kernel 6.15.9-arch1-1

Thanks for your reply.

I got this error during a system update (pacman -Syu). It stopped with exit code 6 when trying to install the facetimehd DKMS module. The update didn’t complete fully because of this.

You're right that the module seems to already be present (facetimehd.ko.zst exists), but since the installation aborted with an error, I wasn't sure whether this could lead to problems later on.

The camera does seem to work after reboot, so maybe everything is fine. I just want to be sure that the DKMS error is harmless and that I don't have a misconfiguration that might cause trouble in a future kernel update.

Any advice on how to properly handle this kind of DKMS situation would be appreciated.

Thanks again!
