Updating kernel: vmlinuz in /boot not being created by DNF

Question

Brand new F23 install, trying to update the kernel. I did lose power during the first round of dnf update and have to go clear out a bunch of conflicts that dnf kept reporting. It's possible I removed something that's needed, to be totally honest here.

Anyways, I've tried both dnf update and dnf install kernel (after dnf remove kernel). They install the latest kernel to /lib/modules/4.4.9-300.fc23.x86_64/, but no new vmlinuz files end up in /boot, so grub2-mkconfig won't find it and use it.

Any suggestions as to where I could start troubleshooting this?

ensure /etc/machine-id exist and is valid/not empty
test -s /etc/machine-id

instead "kernel-install" command will not provide kernel below /boot

from systemd package
called in kernel-core rpm post-install script (rpm -qp --scripts kernel-core-*.rpm)

reinstall kernel-core package then
dnf reinstall kernel-core

dnf reinstall kernel-core

vmlinuz file is provided by kernel-core package so you will need to reinstall it

Ended up updating to the F24 beta, as it's being frozen anyways. This fixed the problem, and I'm now running on the 4.7 kernel.

I'd try

dnf reinstall kernel

or (better)

dnf reinstall kernel-4.4.9-300

since it's possible that dnf has status saying that the given set of files is complete.
