Can't install Plasma Discover - Kubuntu 16.04

[deadtom]

When I do an apt-get upgrade, I get this:

The following packages have been kept back:
plasma-discover plasma-discover-common plasma-discover-private
plasma-discover-updater
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.

If I try to install them, I get this:

$ sudo apt-get install plasma-discover plasma-discover-common plasma-discover-private plasma-discover-updater

Does anyone know how to get passed this?

When the necessary auxiliary packages have been uploaded by the devs that msg will go away and the pkgs will be DL’d and installed.

use

apt full-upgrade

, or

apt-get dist-upgrade

as using plain "upgrade" does not install anything new, just upgrades to existing packages. Also, if you haven't already, be sure to run

apt update

first.
