Thanks for your answer!
Yeah, I don't need it, I just wanted the notifications (which I have connected for "healt_h issues" through Telegram) to stop.
Regarding your Windows comment, according to the wiki:
Alright, so... I actually made it work this way:
add this line after the export that's aldready in there:
I am not sure if this runs on every boot / service startup.
But you can also add this to /storage/config/autostart.sh so that it executes on boot:
so it should become like this:
# whatever other commands you might have in there
Copy fpcalc (I got it for x86_64 from the Chromaprint package) to /storage/.kodi/addons/service.lidarr/bin and give it executable permissions.
This works well for me.
An alternative is to mount / as writable, copy fpcalc to /bin and that will work right away. BUT that may (will probably) be overwritten on system update.
