Adding an openHAB dashboard tile for 'grafana'... FAILED (openHAB or config folder missing)

Release = Raspbian GNU/Linux 10 (buster)
Kernel = Linux 5.4.83-v7l+
Platform = Raspberry Pi 4 Model B Rev 1.2
openHAB 3.0.0-1 (Release Build)

I am new to OpenHAB and running a fresh install of OH3.
When installing InfluxDB and Grafana via openhabian-config, I get following error

Adding an openHAB dashboard tile for ‘grafana’… FAILED (openHAB or config folder missing)
I retried several times but the error keeps on showing up.
How can I resolve this error.

Thanks in advance for your help.

My first guess is that this is a problem because of the you wrote you installed OH3 but you use the ‘stable’ tree.
For OH3 you need to use


in /etc/openhabian.conf

Without further checking the code I assume that this leads to missing directories a la /etc/openhab vs. /etc/openhab2.
So first make sure that you use openHAB3 tree and check if the error still occurs.

Thanks for the info.
That solved the problem but only after remove and purge of grafana
