I have symptoms like you, but my problem is described in #572824. Additionally I change my /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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/655479 Title: People Nearby account cannot send messages -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
