In Ubuntu, this is `dkms`. If you're like me and force reboot shortly after performing an update, then you might have not given akmods enough time to compile any extra kernel modules (for example: Nvidia). This meant that I had to boot into an older kernel to try to fix the problem.... Once in the older kernel, you can check the kernel versions by: ```bash ls /usr/src/kernels/ ``` Then select the kernel which you failed to build and run: ```bash sudo akmods --kernels 5.15.18-200.fc35.x86_64 ``` to trigger the rebuild. Though the better solution is to avoid this problem to begin with. If you `reboot` not as root, then systemd will check to see if any process is inhibiting the poweroff. If that's the case, wait patiently and don't type `sudo reboot`.
