The problem is, that there may only be one route for 169.254.0.0/16. So if there is more than one interface the route will probably already exist on the first interface. The solution is not to set a new route if the route exists on any interface (not only the given one).
To fix this problem: In /etc/network/if-up.d/avahi-autoipd look for [ "`ip route show dev $IFACE | grep ^169.254.0.0/16`" ] && exit 0 (should be line 23) and replace this line with [ "`ip route show | grep ^169.254.0.0/16`" ] && exit 0 ** Changed in: avahi (Ubuntu) Status: Incomplete => Confirmed -- avahi-autoipd causes failure if multiple networking stanzas exist https://bugs.launchpad.net/bugs/84580 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
