[DESKTOP] Wonkiness with dependencies in 5.8.2

[Tahaan]

I'm running Neon User Edition but I've had an absense of a few days to look at Kubuntu 16.10

I came back to find about 170 updates waiting.
After upgrading I noticed AGAIN there is a package being held back, "neon-desktop" of all things.

So to start I removed the "Automatically installed and no longer needed packages" - about 7 in all.

Immediately after that the upgrade command apt tells me there is 1 more package to remove and 1 to add and 1 held back.

The held package is still neon-desktop.
The tug-of-war package is xserver-xorg-video-intel-arbiter which wants to be alternately installed and removed.

It looks like there is a new "clash-of-dependencies" causing xserver-xorg-video-intel-native-modesetting:amd64 to be held back.

xserver-xorg-video-intel-native-modesetting:amd64 can't be upgraded because:

The following packages have unmet dependencies:
 xserver-xorg-video-intel-native-modesetting : Conflicts: xserver-xorg-video-intel but 2:2.99.917+git20160325-1ubuntu1.1 is to be installed
                                               Breaks: xserver-xorg-video-intel but 2:2.99.917+git20160325-1ubuntu1.1 is to be installed

And neon-desktop refuses to upgrade because:

The following packages have unmet dependencies:
 neon-desktop : Depends: xserver-xorg-video-intel-native-modesetting but it is not going to be installed

And for now apt upgrade wants to remove intel-arbiter and holds back neon-desktop:

The following package was automatically installed and is no longer required:
  xserver-xorg-video-intel-arbiter
Use 'sudo apt autoremove' to remove it.
The following NEW packages will be installed:
  xserver-xorg-video-intel-arbiter
The following packages have been kept back:
  neon-desktop
0 upgraded, 1 newly installed, 0 to remove and 1 not upgraded.

Sigh....


Oh I almost forgot to mention: On the shut-down "splash screen" it says I'm running 5.8.2 but on the booting up spash screen it says I'm running 5.8.1. kinfocenter says I have 5.8.2.

A-ha.

Adding intel-arbiter back in, then installing native-modesetting causes the package manager to remove xserver-xorg-video-intel, after which neon-desktop could be installed... There was a scary moment in there where the package manager seemed a bit uppity about the whole thing:
