Uninstallable Dependencies

[MM347]

Hi all, wondering if someone smart can point out what's going on here.

My Environment:
php:8.2.7-apache-bullseye docker container (also tried 8.1.8)
Debian 11 Bullseye
PHP 8.2.7 (also tried 8.1.8)

Then following instructions here: Download and install Zabbix 7.0 PRE-RELEASE for Debian 11 (Bullseye), MySQL, Apache
2 Requirements (zabbix.com) clearly shows PHP support for 7.4.0 - 8.2.X and urges away from 7.4. So the PHP I'm using should be in scope. However the below dependencies all seem to require 7.4.

zabbix-frontend-php is failing to install. Same result with Zabbix 6.4 and 7.

The following packages have unmet dependencies:
zabbix-frontend-php : Depends: php-mysql but it is not installable or
php-pgsql
Depends: php-mbstring
Depends: php-bcmath
Depends: php-xml
Depends: php-gd
Depends: php-ldap
E: Unable to correct problems, you have held broken packages.

I've used aptitude to troubleshoot and after installing php 7.4 and a load of other shenanigans I got it working but it seems an unintended step, possible bug and not something I want in a container, as it seems a bodge job.

Probably done something daft, would appreciate another set of eyes.

For some reason the Docker PHP Debian image stops Debian PHP installs...
To fix: rm /etc/apt/preferences.d/no-debian-php
