Server not starting

Hi,
I tried to install the latest versions, OSS and enterprise on a new machine.
Ubuntu 22.04.3 LTS. I did it serveral times following divers instructions. I always tried to clean the machine before the next installation. I have experience with Grafana for many years. Not very deep but I am not a newbee.
My problem: promt hangs after starting grafana server. I cannot find any logs. Port 3000 has status closed. No change on the ini.
Any tips for me?
Thank you, Ralf

welcome @ralf51

could you give more details about how you installed both OSS and Enterprise Grafana (as well as the links to the installation instructions) ?

thanks
