I'm noticing the same behavior. For a while I see DNS requests from the build in dnsmasq being sent to the forwarding DNS servers (either as set by DHCP or manually in the network manager config) and responses coming in just fine. After a while however I only see the request packets being sent on my ethernet interface, but no response packets being received on my network interface (as shown by wireshark).
However it does look like disabling the build-in dnsmasq in network manager fixes the problems for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589005 Title: After update DNS work unstable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1589005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
