Public bug reported:
After a while / after resume from suspend, the system becomes unable to
respond to DNS queries, with the following output for example:
$ nslookup google.com 127.0.1.1
Server: 127.0.1.1
Address: 127.0.1.1#53
** server can't find google.com: REFUSED
This is on an up to date yakkety install. Changing resolv.conf to use 8.8.8.8,
or restarting network-manager appears to fix this, at least until it recurs
again.
