as it turns out sonarr was installed in /opt/Sonarr and not in /opt/sonarr/Sonarr
so i changed the path and it worked.
but i lost al the v3 DB and had to re configure from scrach ☹️

dietpi-software installs Sonarr v4 to /opt/sonarr. How did you originally install and migrate it?

On a test migration I also lost the one test series I added. Sonarr docs state that I attempts to migrate as much as possible and also firat startup logs show a database migration. So I also was confused. However one can import everything from the download directory structure, at least.

yep thats what i eventually ended up doing.

i installed v3 a while ago via dietpi-software as i also did this time (v4).
but it was installed in /opt/sonarr/Sonarr thats why i got this error.

regarding the database i did a manual backup before the upgrade an after i got sonarr to start in was a blank database, so i tried to restore from a backup but it hanged so i had to completely reinstall it and manually add al the shows from scratch.

/opt/sonarr/Sonarr is however perfectly right, but we forgot to adjust the ReadWritePath= directive in the systemd unit. The bug was solved here, including a live patch: #7326
