F27 updater problem

edit

I ran into this problem last week when trying to update to kernel 4.14.8. It just happened again when I tried to update the kernel.

I tried to update to kernel 4.14.11. dnfDragora crashed almost immediately. When I re-open dnfDragora it doesn't show any available updates.

Apper crashed when installing the kernel then came back and updated Chrome successfully.

Going to a terminal and doing dnf -y update tells me there is nothing to update. I don't think this is accurate but the system rebooted to the new kernel successfully. How do I tell when the system successfully updated if the updaters fail?

I'm running F27 workstation, 64bit, KDE/Plasma desktop
