I've filed a bug about this here:
Fedora 27 offline updates (gnome-software intitiated) are failing
This is on a system upgraded a couple weeks ago with 'dnf
system-upgrade' from Fedora 26 to Fedora 27.
I've receive a notification there are updatess, so I go into Gnome
Software, choose Restart & Upgrade from within Gnome-Software, it
reboots and plymouth gives me the updating indication and status, and
pretty much immediately I get a reboot.
Once rebooted, it's clear the updates have not been applied.

system-upgrade reboot' to begin the upgrade

[ 6.356983] f27h.localdomain systemd: Rebooting: service failed
Why is dnf saying to use 'dnf system-upgrade reboot' for a minor
update? I'm not asking for an upgrade, that's already been done and it
