WORKAROUNDI already have RBFeeder installed on my other Pi (Raspberry Pi) running
Raspbian Jessie.
I copied RBFeeder's .deb file from Raspbian Jessie/Raspberry Pi, and using it, installed RBFeeder on Ubuntu Xenial/OrangePiPC successfully:
NOTE: In code below, the IP 192.168.0.21 is local IP of my Raspberry Pi/Raspbian Jessie. Replace it by local IP of your Pi running Raspbian Jessie (or Raspbian Stretch) on which Radarbox24 feeder has been installed already..
#First find the location and full name of rbfeeder installation package in RPi/Raspbian Jessie
pi@raspberrypi:~$ sudo find / -name rbfeeder_*
/var/cache/apt/archives/rbfeeder_0.2.3-20170527202345_armhf.deb
#Now copy this file to OrangePiPC/Ubuntu Xenial
