Dependencies errors after upgrade KDE Neon Xenial to Bionic

[lighttemplar]

I did upgrade from KDE Neon Xenial to Bionic. It went with problems because of postfix configuration bug (konsole window must be wide open), so I should restart it and continue manually. dpkg --configure -a went good.
Now, as I have my laptop restarted and launched sudo apt update && sudo apt full-upgrade

I don't understand messages, it lists all the same versions but compares xenial against bionic.

How can I solve this puzzle?

apt suggests to remove such packages as kwin, plasma-desktop, discover and kinfocenter - are they really thrown away in Bionic?

Thread moved to Ubuntu/Debian BASED.

So, I made some steps, now there are less problems.
First, I removed some packages from hold back, which looked old for me: simple-scan and subtitlecomposer
then I found, that many of packages have higher versions, than those in the ubuntu bionic repositories. And I realized, they was installed from Padoka PPA. So I downgraded them with help of ppa-purge.

For now I have much less errors.

and the rest was actually simple. I did let apt do, what it wanted, and then last four [colord, cryfs, orthanc, gimagereader] package for package removed, looked, what depends on them, corrected ppas and removed another one package, which I had from .deb installed.

Congrats me, I did upgrade!
Now remains the last simplest task: enabling rest ppas.
We can mark it as solved.

Just for logs:
I had to remove masterPDF, to enable and change repository for R-Project, reinstall Zulucrypt and something else a little, can't remember

We can mark it as solved.

You can do that under the Thread Tools menu at the top of the page, and thank you.
