Firmware Update Deamon. This wonderful utility/service creates a
consistent means for hardware vendors to provided and apply firmware
updates to devices. Dell is on board and now so is Logitech.
The tools and infrastructure a written by the developer that created and
released the ColorHug. The ColorHug is an open source color measurement
device for monitor color calibration. He initial was fixing his own need
to provided easy firmware updates to the ColorHug.
fwupd came on my radar a few months ago, when there was news reporting
about improved Thunderbolt 3 support for the Dell laptops, and fwupd was
the delivery mechanism. But at the time I didn't have any Dell laptops,
so it was just a curiosity.
Now what I do have is a lot of Logitech K400 keyboards, and no easy
means of updating the vulnerable firmware. fwupd now changes that.

My Experience
=============
[scott@failfast ~]$ sudo dnf install fwupd
# This got me version 0.7.5-1.fc25, which didn't quite work out of box.
No matter, were upgrading anyways.
[scott@failfast ~]$ fwupdmgr get-devices
Error calling StartServiceByName for org.freedesktop.fwupd:
GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Launch helper

[scott@failfast ~]$ sudo dnf update fwupd --enablerepo=updates-testing
