I added a PPA for KUbuntu backports to Zorin which had newer versions of most of the KDE packages.  By applying those upgrades it is now mostly functional.  Powerdevil explodes but so do similar packages in other window managers and I think the reason is that it is running in a virtual machine, it has no real hardware to twiddle.  I would just remove it but like the other window managers there are stupid dependencies that require it’s non-functional presence for other things to work.  A similar situation exists with some bluetooth packages.  No actual hardware but if they aren’t here dependencies break other things.
