Installation of InfluxDB aborts via openhabian-config

Hi Wolfgang,

thanks for your hints, that sounds simple…

But:
InfluxDB instructions copy&paste via SSH, no errors
Grafana instructions copy&paste via SSH, error at the second command “persmission denied”

Nonetheless started the installation routine in openhabian-config, but I’ve got the same error again:

 There was an error or interruption during the execution of: "20 | Optional Components"
