[Solved] Gitea Installation Fails with Database Error

guide 7.2
I also followed this guide to install gitea, but also failed with:
Datenbankeinstellungen sind ungültig: Error 1045 (28000): Access denied for user 'gitea'@'localhost' (using password: YES)

I managed to change my global password with instructions in toml file found here and restarted dietpi-dashboard.service.

It always says MariaDB but my config page says MySql.

Also all the pathes given are not existent and so does the

/run/mysqld/mysqld.sock

Where is the database storage folder?
And also I have already a working git repo configured in /home/git/git… Can’t I use this also for gitea or do I have to use the default places. I also have found gitea artifacts in /home/git/gitea…

But anyway I am stuck and nothing works.
