Hello,

I have been working on an issue with rpos. I have a Raspberry PI3 compute module with the (old) Jessie OS installed running rpos with no problems.
When I do an in-place OS upgrade from Jessie -> Buster then try to run rpos I get the following error:
Starting camera settings webserver on http://192.168.2.10:8081/
Binding MediaService to http://192.168.2.10:8081/onvif/media_service
Binding PTZService to http://192.168.2.10:8081/onvif/ptz_service

Steps to Reproduce

  1. Start with a working install of rpos on the raspberry PI Jessie OS
  2. Run rpos using the following command 'sudo node rpos.js'
  3. Not starts successfully
  4. Perform an in-place OS upgrade using the following steps
    sudo echo "deb http://mirrordirector.raspbian.org/raspbian/ buster main contrib non-free rpi" > /etc/apt/sources.list
    sudo echo "deb http://archive.raspberrypi.org/debian/ buster main ui" > /etc/apt/sources.list.d/raspi.list
    sudo apt-get update
    sudo apt-get --yes --force-yes -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" dist-upgrade
    (Wait ~50 minutes for the install to finish)
  5. Reboot the system
  6. Run rpos using the following command 'sudo node rpos.js'
    Here is the output I am seeing:

Other Notes
I tried a number of different things to resolve this issue.

  1. I was using an older version of rpos so I did a 'git pull' to update to the latest version, no luck
  2. I changed the port from 8081 to 8082 and I got the same result
  3. I performed an analysis on the used ports 'sudo netstat -tulpn'
    I found the following ports in use after a reboot on buster
    Active Internet connections (only servers)

    udp6 0 0 :::45291 :::* 448/avahi-daemon: r
    As you can see, there is no current usage of port 8081
  4. Attempted to remove and re-install rpos (this failed miserably, it seems that rpos is can no longer be installed, I filed a separate defect report on that issue)

At this point I'm not sure what else I can do.

If I can get help with this, that would be great!

Thanks,
