[Bug 1548817] Re: package sddm (not installed) failed to install/upgrade: Unterprozess installiertes post-removal-Skript gab den Fehlerwert 128 zurück

@ bitbull:

I honestly think this is the outcome of bug 1451728. Tending to mark as
duplicate, since there is no real relation to SDDM.

A lot of things went wrong during your attempt to deinstall the kubuntu-
desktop, saying so after going through the attached DpkgHistory.log

Given the fact that probably the package-manager in use wouldn't give
visual feedback, the log provided sufficient information valid for a
multi-desktop environement (as it's easy to install, but hard to get rid
of) -> Make sure to install/switch to GDM.

And in final make sure to reinstall gnome-desktop, since the
deinstallation teared away most needed packages for a functioning
environment.

Not knowing if u have come back to a functional desktop, I would
recommend  to join the ubuntusers.de Forum for assistance. There are
great people with a broad knowledge considered to help. Anyway your
system should be recoverable with the chroot-method by using a Live-CD
(same release and architecture). This is described well in
https://wiki.ubuntuusers.de/chroot/Live-CD/

I can honestly not understand why Kubuntu-devs didn't make accounts-
plugins/kaccounts-providers conflict, when this error appeared.  This
would have avoided a considered amount of troubles for a lot of people.

The common ratio of bugs beeing reported is 1:100 to the ratio of people
beeing affected. Having said so, you are welcome if you need any further
assistance to recover your system.
