i can say that original script doesnt work anymore at least for me on ubuntu 20, because of multiple factors like i.e. ondrej sury ppa doesnt hold php7.0 for ubuntu 18 and 20 anymore and also the way that build.xml in ministra www data is written, but i managed to edit it to the point that it installed and runs on ubuntu 22.04 and i can confirm it works with formuler boxes as expected. As for official ministra apps, you need subscription for the app not for ministra portal connection, so without it, it wont work, you would need modded official app that has that removed, but i didnt find any so far...
