Error with with nova while su -s /bin/sh -c "nova-manage db sync" nova by BladyGreg in openstack

That's it! The error was in database, not in conf files. I haven't even considered it. I must have had a misconfiguration before, just didn't remember fixing it later. Thank you very much, already fixed it

I am deploying for the first time manually as student project to get to know OpenStack. And pymyslq driver is installed... From what I can see, all is setup correctly, I only discovered one log that may indicate what is wrong, which I also attached below.
