** 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 - --- - 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 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/1874021 Title: avahi-browse -av is empty, mdns not working in arduino ide Status in avahi package in Ubuntu: Incomplete Bug description: When I started the arduino IDE my port list is empty.
