Hi,
ubuntu 18.04 , I checked installation version from composer and also from zip file, same error.
I checked also configuration by shell script, didn't help. I don't know what to do... I am not sure if it ask about super admin account from uvdesk or the symfony framework, I found some ideas on forum like changing url parameter add/remove "resolve" in config file doctrine.yaml, but that didn't help also.
I am quite sure or chmods done correctly, php limit set in php.ini, and also permission apache to override set on ALL.
Please check it guys, I sucked.
