Problems to satrt gitea after install

Problems to start gitea after install.
In my journalctl I see this

kt 25 12:28:41 raspberrypi systemd[1973679]: gitea.service: Failed to locate executable /usr/local/bin/gitea: No such file or directory
Okt 25 12:28:41 raspberrypi systemd[1973679]: gitea.service: Failed at step EXEC spawning /usr/local/bin/gitea: No such file or directory

But I have installed gitea in /opt/gitea and this is also declared in my Gitea Systemd Service file. So which path I have also to change that gitea find the right install place?
