I have a development system that started off as a 15.2 system and was successfully upgraded to 15.3. The system is a Web Server using apache 2.4 php7.4 and php-fpm. Everything worked after that upgrade, but now after the upgrade to 15.4 the php apps will not take file uploads. I tried raw php and my Laravel apps, I get the same results.
I suspected AppArmor, but I have tried everything and nothing works. It seems like the files are not making it to the system. Is there something common that I could be overlooking?
