** Attachment added: "ProcEnviron.txt"
https://bugs.launchpad.net/bugs/1874021/+attachment/5357823/+files/ProcEnviron.txt
** Description changed:
When I started the arduino IDE my port list is empty. This list relies
on multicast DNS which is served by avahi.
When running the avahi-browse -av command on ubuntu 18.04 I get a list
of al mdns devices. On ubuntu 20.04 the're no mdns devices reported.
The avahi-daemon is running. And when executing netstat -nlp | grep 5353
I see avahi-daemon is listening. When also running tcpdump port 5353 I
see mdns packages arriving. But still avahi-browse -av is empty.
iptables -A shows no rules and policies are accept
ufw is disabled
I also removed apparmor but also that didn't make any difference.
On both ubuntu 18.04 and 20.04 the avahi version is 0.7.
