Install InfluxDB/Grafana fails from Openhabian config tool

You are a genius !
That was it, I should have searched more as it was just 2H ago:

openHABian influxdb+grafana installation error

There seems to be a known problem with third party package influxdb. For more information see e.g. this thread: https://community.openhab.org/t/oh-3-1-0-influxdb-stopped-working-after-update-to-1-8-7-1/125042/ You can fix it by running: sudo chmod +x /usr/lib/influxdb/scripts/influxd-systemd-start.sh sudo systemctl restart influxdb.service
