Public bug reported: I upgraded from 12.04 to 14.04 and found that I had no DNS. After a little searching I noticed that dnsmasq, as started by Network Manager, was listening on 127.0.1.1, yet /etc/resolv.conf was being auto- populated with 127.0.0.1, so DNS lookups were failing.
Manually adding 127.0.1.1 to /etc/resolv.conf lets DNS work until the network state changes, then it gets overwritten again with 127.0.0.1. I've worked around the issue by adding "nameserver 127.0.1.1" to /etc/resolvconf/resolv.conf.d/head and restarting network-manager. Something left over from 12.04 is apparently still causing 127.0.0.1 to be written instead of 127.0.1.1. ** Affects: resolvconf (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315741 Title: After upgrading from 12.04 to 14.04, network manager puts 127.0.0.1 instead of 127.0.1.1 in resolv.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/1315741/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
