+++ I had the same problem as described above.. after doing "sudo dpkg-
reconfigure resolvconf" everything appears to be OK now. Repro and diag
info below +++
- Setup a new box with www.Linode.com. Took their image of: Ubuntu 12.04 LTS
64bit.
## Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.5.2-x86_64-linode26 x86_64)
- Immediately after it was online: apt-get update && apt-get upgrade
- Installed OpenVPN and created a new /interfaces bridge
- NOTE: My IP address for eth0, well now br0, is DHCP... (so, later when told I
should add entries for dns-nameservers in /etc/network/interfaces, I did
nothing)...
>> then, I got "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing
>> anything":
root@localhost:/# sudo /etc/init.d/networking restart
* Running /etc/init.d/networking restart is deprecated because it may not
enable again some interfaces
* Reconfiguring network interfaces...
Ignoring unknown interface eth0=eth0.
Waiting for br0 to get ready (MAXWAIT is 18 seconds).
resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything.
ssh stop/waiting
ssh start/running, process 11457
[ OK ]
