Error Upgrading to Kernel 6.8.4-3 with 6.5.13-5 Pinned with DKMS i915 Driver Installed

[SInisterPisces]

Hello!

I'm currently running Proxmox 8.2 with the 6.5.13-5 kernel pinned so I can make use of SR-IOV-based Intel iGPU passthrough.

I've already upgraded the 6.8 kernel (which I'm not using) once with this setup, and it seemed to work fine, but when I ran a system update today, I got an error.
tl;dr I got a somewhat concerning error on system update and want to make sure I haven't damaged the 6.8.x kernel install.

That's ... ominous.

I don't expect the dkms driver to try to install itself into 6.8.x kernels. Not only will that not work (it's not supported), I pinned the kernel to keep that from happening.

On reboot, apt update told me I had two "partially installed" packages which I assume are the kernel and header packages mentioned above, but when I ran apt update again, I didn't see that.

Now, searching for the kernel and header packages shows me this:
