I can confirm that for this bug, I am not affected directly by suspend / resume actions. But the DNS still randomly fails during normal operation of the machine.
If I kill dnsmasq PID and restart it from the command line, then it works again. sudo /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/NetworkManager/dnsmasq.pid --listen-address=127.0.1.1 --cache-size=0 --conf-file=/dev/null --proxy- dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf- dir=/etc/NetworkManager/dnsmasq.d & -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639776 Title: dnsmasq fails to send queries out after suspend disconnects the interface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1639776/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
