Fix NVIDIA DKMS build failures after upgrade
A kernel upgrade made the NVIDIA DKMS build fail. The log DKMS leaves under /var/lib/dkms names the real cause. Here is how to read it and fix it.
Fix NVML driver/library version mismatch
nvidia-smi fails with Driver/library version mismatch when an upgrade replaces the NVIDIA libraries under a loaded kernel module. Diagnose it, then fix it.
Fix NVIDIA 'key was rejected by service'
Secure Boot refuses unsigned NVIDIA modules, so DKMS builds fine and modprobe still fails. Check firmware state, then enrol a MOK or stop enforcing.
Fix NVIDIA driver not loading on Ubuntu Server
nvidia-smi cannot talk to the driver. Walk the ladder: lsmod, dmesg, dkms status, then fix missing headers, nouveau, a kernel update or Secure Boot.
Jellyfin NVIDIA hardware transcoding in Docker
Give a Jellyfin container an NVIDIA GPU with Docker Compose, turn on NVENC and NVDEC, and prove the GPU is really transcoding with nvidia-smi.

Run NVIDIA Nemotron 3.5 Lightning with Ollama on your own server: the exact tag to pull, how much RAM it needs, and if CPU-only is fast enough.
