Title:
Symlink /etc/resolv.conf does not exist after installation or upgrade
of resolvconf -- various causes
Status in Release Notes for Ubuntu:
New
Status in “resolvconf” package in Ubuntu:
Confirmed
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.
