** 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. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27 + Architecture: amd64 + CasperMD5CheckResult: skip + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 20.04 + InstallationDate: Installed on 2020-04-08 (13 days ago) + InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Beta amd64 (20200402) + Package: avahi-daemon 0.7-4ubuntu7 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.4.0-25.29-generic 5.4.30 + Tags: focal + Uname: Linux 5.4.0-25-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dialout dip lpadmin lxd plugdev sambashare sudo + _MarkForUpload: True + modified.conffile..etc.default.avahi-daemon: + # 1 = Try to detect unicast dns servers that serve .local and disable avahi in + # that case, 0 = Don't try to detect .local unicast dns servers, can cause + # troubles on misconfigured networks + AVAHI_DAEMON_DETECT_LOCAL=0 + AVAHI_DAEMON_START=1 + mtime.conffile..etc.avahi.avahi-daemon.conf: 2020-04-21T09:03:32.502101 + mtime.conffile..etc.default.avahi-daemon: 2020-04-21T09:11:39.632727 ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1874021/+attachment/5357817/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874021 Title: avahi-browse -av is empty, mdns not working in arduino ide To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1874021/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
