Public bug reported: I upgraded an 11.10 install to 12.04, and now I'm unable to resolve domain names because Network Manager does not populate my /etc/resolv.conf file.
For example, my local wireless router uses the domain "mylocaldomain" and nameservers 10.157.10.12 and 10.157.10.14, so in 11.10, after connecting to the router I would see this in my /etc/resolv.conf: domain mylocaldomain search mylocaldomain nameserver 10.157.10.12 nameserver 10.157.10.14 Now /etc/resolv.conf contains the settings last set before I upgraded to 12.04, and doesn't update them for whatever network I'm currently on. I have to manually guess the settings and modify /etc/resolv.conf in order to resolve domain names. I believe this may be related to https://bugs.launchpad.net/ubuntu/+source/resolvconf/+bug/922677 and how the "resolvconf" program has been introduce to manage this. I believe this is a new bug with how prior installs are improperly upgraded. I tried removing the line "dns=dnsmasq" from /etc/NetworkManager/NetworkManager.conf and then running `sudo restart network-manager`, but that had no effect. I tried running `resolvconf --enable-updates` but I get the error "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." Based on https://help.ubuntu.com/12.04/serverguide/network- configuration.html#name-resolution, I tried establishing this symlink myself, but the file /run/resolvconf/resolv.conf does not exist on my system.
