Thomas,
>You say that your setup is "partially" fixed. What part is not fixed?
When I initially applied pdf's fix, I was able to resolve external
domains, but not internal domains. However, this seems to have resolved
itself, so now it seems my setup is completely fixed.
Also, the output of those commands are:

Title:
resolv.conf not populated because /etc/resolv.conf symlink was not
created
Status in “resolvconf” package in Ubuntu:
Incomplete
Bug description:
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.
