[Bug 1000244] Re: /etc/resolv.conf symlink does not exist after initial installation of resolvconf package

Sun Sep 2 11:35:00 UTC 2012

I have done a new installation with Linux Mint Maya (MATE-32 bit) and again I have the same issue (no /etc/resolv.conf created).
This time, it is a brand new installation. No Updates installed, no VPN software added. 
Running "sudo dpkg-reconfigure resolvconf" fixes the issue (I have "yes" to both questions that appear)
Let me know if you want me to perform other tests (I'll try to answer sooner) and thanks for your work.

Title:
  /etc/resolv.conf symlink does not exist after initial installation of
  resolvconf package

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.
