Hi,

running KDE neon User Edition here (installed from neon-useredition-current.iso).

As far as I can tell, there should be an app called "Update Manager", see following screenshot: https://2.bp.blogspot.com/-P1qUTBh9Qac/VxEr62zv1nI/AAAAAAAAE8g/QMYEB2zCu3MxiW1OUja8BeNr9HedxNSBwCLcB/s1600/11%2BSoftware%2BUpdate%2BManager.jpg (Source: http://www.distroscreens.com/2016/04/kde-neon-1604-14-04-2016-screenshots.html )

And according to the following page, apparently it should be provided by the package "plasma-discover-updater", see: https://wiki.ubuntuusers.de/Plasma_Aktualisierungsverwaltung/

Apparently it should be available via Applications -> System -> Update Manager.

But it's not there. According to muon, the status of that package is "Installed".

However, when trying to start it from the terminal I get:

user@machine:~$ plasma-discover-updater
The program 'plasma-discover-updater' is currently not installed. You can install it by typing:
sudo apt install plasma-discover-updater

When trying that, I get:

Then:

user@machine:~$ plasma-discover-updater
The program 'plasma-discover-updater' is currently not installed. You can install it by typing:

What's going on there? Could you please fix it?
