I’m getting this comitup error as well. The comitup process is failing and restarting continuously, using 40 to 50% cpu. I’ve only had one reboot. It seems to be installing, but very slowly.
I had wanted to installed over wifi, but could not get that to work. It seems that comitup ignores /boot/wpa_supplicant.conf. I finally got it to connect over ethernet.
You can also disable it via systemctl disable comitup but comitup will only fire up if there’s no connectivity.
So get your Wi-Fi right and it should disappear. And use openhabian.conf/openhabian-config for that.
Force of habit. /boot/wpa_supplicant is how I’ve always configured Rpi wifi. Once it was updated over ethernet, it then let me configure the WiFi over comitup’s web. I logged comitup’s constant restarting as a bug on github.
My interpretation of the error log is that comitup is trying to open port 80 while some other process, or a previous instance, has it open already.
I’m doing a trial install on an old pi 3 so that I can familiarize myself with openhab 3.1 before upgrading my 2.5 system. When I do that install, I’ll look into the comitup error more, should it pop up.
