Editing /etc/default/avahi-daemon fixed it for me. AVAHI_DAEMON_DETECT_LOCAL=0 makes it discover all 8.10 machines in my lan (and others machines are now able to see the upgraded one).
Possible cause for problem might be D-link nat router which has built in dns proxy. I don't realy know but that is my best guess. -- avahi-daemon disabled because there is a unicast .local domain https://bugs.launchpad.net/bugs/327362 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
