@Fernbace We have checked the Restyaboard installation log file and while trying to install the PHP 7.4, dependency error thrown

The following packages have unmet dependencies:
php7.4 : Depends: libapache2-mod-php7.4 but it is not going to be installed or
php7.4-fpm but it is not going to be installed or
php7.4-cgi but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

We have also checked with New Ubuntu OS with version 20.04 and the Restyaboard working correctly

Please check about the dependency issue

since I didn't want to further mess with the production system I tried installing from scratch on a Ubuntu 20.04 system. Since this system had apache already set up, I went with the apache option.
restyaboard_install.log
The logfile is attached. The result was the same, blank screen in the browser.
line 3790 of the log has:
psql:/var/www/html/restyaboard/sql/restyaboard_with_empty_data.sql:30: ERROR: must be owner of extension plpgsql

I wouldn't know how to fix that.

In line 584ff it says:
To enable PHP 7.4 FPM in Apache2 do:
a2enmod proxy_fcgi setenvif
a2enconf php7.4-fpm

which I did manually
