FIrst, I'd like to know exactly what /etc/network/if-up.d/000resolvconf
is receiving in the IF_DNS_NAMESERVERS variable. Please apply the
appended patch, down and up the br0 interface, confirm that
/run/resolvconf/interface/br0.inet still contains
nameserver 66.185.16.130
nameserver
nameserver 66.185.16.131
and then post here the lines from /var/log/syslog that look like the
following ones.
Oct 22 22:26:38 myhost /etc/network/if-up.d/000resolvconf: 000 2e31 2e32
2e33 2034 2e35 2e36 2e37 0a38
Oct 22 22:26:38 myhost /etc/network/if-up.d/000resolvconf: 020
Second, what happens if you comment out the bridge_* options in the iface br0
stanza? Does the spurious nameserver line go away?

Well, you actually have to ifdown and ifup the interface (br0) to test properly. But since there are no non-printing characters on the dns- nameservers line I guess my hypothesis has been disproved.

[Bug 1067043] Re: resolvconf adds an empty nameserver record into /etc/resolv.conf
The empty nameserver line comes from /run/resolvconf/interface/br0.inet which was created by the script /etc/network/if-up.d/000resolvconf from the content of the IF_DNS_NAMESERVERS variable whose contents come from the dns- nameservers line in the iface br0 stanza of /etc/network/interfaces. My next guess is that the dns-nameservers line contains one or more non-printing characters between the first and the second listed IPv4 address. Can you please check? If there are such characters, what characters are they? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067043 Title: resolvconf adds an empty nameserver record into /etc/resolv.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1067043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
