OTA not showing up Debian 10 Arduino 1.8.13 openjdk 11

"Open port" shows no network devices.

Two other network computers running Mint 18 and Mint 19 on the same network show the existing network ports. I installed libjmdns-java thinking that might help. It didn't I can't find a avahi browser for debian. I tried avahi-discover and all it showed was my network card. I don't know anything about mdns.


Any help?
Thanks,
Jim
