pckon is driving me mad by telling me over and over again about unmet dependencies, but when I try to install those packages I am told they are installed already.
Below you’ll find an example. (I used “LC_ALL=C” to make the system speak English temporally.)
I can take whatever package I want from the list of recommendations, but the result will always be same: those packages are installed already, ‘dpkg’ will list their contents and ‘ls’ will show those files as existent. My plasma desktop is up and running, until now I have not experienced any crash due to missing files.
How do I solve this misery?
Thanks in advance for any help!

Well, here’s what apt has to say about this issue. It’s basically the same errors that pkcon emits. I can not make sense of all those “fixing”, “adding” and “repairing” messages, because they appear each time I run this command. How many times do these packages need to be added, fixed and repaired??
Furthermore, I never set any packages to be held back, and I never switched the machine off just using the main switch and thus killing a possible maintenance of apt’s database. (Last time I had to use the power switch was over 20 years ago! )
And finally, smartmond says nothing about hard drive failures.
So, my guess is that the repository of KDE Neon contains some wrong packages dependencies. But I am open to suggestions how to fix my system.

If so, then everyone would be seeing this problem, or at least many would.
The first half DOES provide more specific info on the specific packages that are being complained about.

And libgpgmepp6 seems relevant as well
I have not deciphered it yet, though.
As to many of the ‘held’ packages, those are being ‘phased’ by Ubuntu. All of the ones you have except for the kwallet related ones are being phased, or have dependencies that are. They are not related to kwallet, as far as I can tell, and I have a similar list of held stuff on one of my neon systems.

If I try to install those packages, apt goes haywire. I can not paste the complete output of the install command, because the forum system tells me it’s twice as much bytes than I am allowed to enter.

Hmmmm… I just had a closer look at the suggested command. There is no libappstream5 to be installed. And even when I leave libappstream4, I get the message about libappstream5, which I find a bit strange:
