Bugreport on Update 20.04, not possible to update

[Jakob Hagedorn]

I got this alert when I tried to update my system:
"Es konnte nicht ermittelt werden, welche Systemaktualisierungen verfügbar sind

Ein unlösbares Problem trat während der Berechnung der Systemaktualisierung auf.

 Wenn keine dieser zutrifft, melden Sie bitte den Fehler mithilfe des Befehls 'ubuntu-bug ubuntu-release-upgrader-core' in einem Terminal. Wenn Sie dies selbst untersuchen möchten, finden Sie in den Protokolldateien unter »/var/log/dist-upgrade« Details zur Systemaktualisierung. Schauen Sie sich insbesondere »main.log« und »apt.log« an."

Sry that it is in german. The Google translator says this:

"It could not be determined which system updates are available

An unsolvable problem occurred while calculating the system update.

 If none of these apply, please report the bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want to investigate this yourself, see the log files under / var / log / dist-upgrade for details about the system upgrade. In particular, look at "main.log" and "apt.log"."

You have installed xorg pacakges from a PPA which is provided version numbers of the packages greater than those which appear in the official Ubuntu archive. You'll need to remove those packages using the tool ppa-purge before the upgrade will be able to be calculated.

Many thanks Brian!
I tried to use ppa-purge. Unfortunately, I have forgotten what exactly was installed from a ppa and cannot find the correct -o or -p name to add.
I tried a dpkg --list to search whether any packages indicate they are from a ppa (probably a stupid idea to you, but this is my level of knowledge)
Which command would help me to learn what the correct ppa-purge would have to be?

I'm not sure there is an easy way to discover this information but one way to do it is to look in /etc/apt/sources.list.d/ for .list files associated with at PPA.

You seem to have used a kisak mesa PPA and lutris team PPA at one point in time.
