Have been running meteohub for many years and want to update my old pi b to a pi 3 b, so I bought a pi 3 b and downloaded the recommended image (5.0s). This boots to a command line login as expected. I can log in as root. The machine has acquired 192.168.20.16 as it's IP address from a hard wired ethernet connection, and for some reason has created 192.168.1.77 as a sub interface (quite why is beyond me - that can never work). Regardless the machine is not listening on port 80 on it's primary IP address. as evidenced by netstat :
root@meteohub-rpi:~# netstat -an

So I guess the question is . . . why ?

As expected I can ssh into the machine without issue, just no admin page being served.
Whay am I doing wrong and does any kind of setup guide exist ? . . . It used to be simple . . . not so any more.
TIA
