Resolved [Plesk installer] The following packages have unmet dependencies: psa-php-configurator

[King555]

When I'm trying to install the "PHP version by OS vendor" (Ubuntu 18) via the console (/usr/local/psa/admin/bin/autoinstaller) I get the following error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
psa-php-configurator : PreDepends: libapache2-mod-php
                        PreDepends: php-cgi

Installation will not continue

I think I know what lead to this error:
- After a fresh installation of Ubuntu 18 and Plesk Obsidian I installed PHP 5.6 via the ondrej/php repository.
- Then I deleted the OS vendor PHP version via the Plesk installer, which deleted PHP 5.6 (I don't know why).
- Then I had to reinstall PHP 5.6.
- Some days ago I uninstalled PHP 5.6, because I migrated my PHP applications to PHP 7.4.
- I remember that "psa-php-configurator" was part of the uninstallation (I could not skip this).

Does anyone know a solution for me?

EDIT: I resolved it by myself. I uninstalled PHP 7.2 (from OS vendor) manually via console, which was still installed. Now I could install it again via Plesk installer. The problem was that there was an inconsistency between Plesk installer (OS vendor version NOT installed) and reality (OS vendor version IS installed).
