It's much more likely that this is due to the update of dnsmasq (https://launchpad.net/ubuntu/+source/dnsmasq/2.73-1):

If that works, then it's a dnsmasq regression, or NetworkManager needs to get adjusted to the newer version. If that doesn't work, can you please try to downgrade to the previous systemd version? This is much less likely to work as systemd doesn't do any network configuration beyond starting NetworkManager (which obviously works) and calling ifupdown (which you don't seem to use). ** Package changed: systemd (Ubuntu) => dnsmasq (Ubuntu) ** Changed in: dnsmasq (Ubuntu) Status: New => Incomplete ** Summary changed: - NSEC3: verify failed due to bad signature (keyid=33878): RRSIG validity period has not begun + NetworkManager[792]: <warn> dnsmasq not available on the bus, can't update servers. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1470028 Title: NetworkManager[792]: <warn> dnsmasq not available on the bus, can't update servers.
