[Bug 1018271] Re: unexpected prompt for nameserver IP when using DHCP

[Jonathan Marsden]

Here is a tar.gz tarball of /var/log/installer as requested.

I'm trying to think what other information might be relevant to this.
Host PC is running Ubuntu 10.04.3 LTS amd64.  VM is set to Bridge mode,
not NAT mode.  DHCP is provided by the Verizon supplied router that
comes with my Verizon FIOS Internet service.

But what is odd to me is that the i386 ISO apparently does the right
thing, only the 64bit one seems to have the issue.

Anyway, I hope this helps!

Title:
  unexpected prompt for nameserver IP when using DHCP

Status in “debian-installer” package in Ubuntu:
  New

Bug description:
  Ubuntu release:

  Testing Lubuntu Quantal 12.10 Alpha 2 Alternate amd64 image from
  http://cdimage.ubuntu.com/lubuntu/daily/20120627/quantal-alternate-
  amd64.iso .

  Testing was done in a virtualbox 4.1.16 VM.

  Package version:

  debian-installer 20101020ubuntu150

  Expected Behaviour:

  After DHCP configuration, no manual provision of network information
  should be requested, the installation process should continue to disk
  partitioning etc.

  Actual (unexpected) Behaviour:

  During the install process, after a message that DHCP
  autoconfiguration was successful, a dialog with the title "[!!]
  Configuring the network" is displayed which asks the user for a list
  of nameserver IPs.

  This issue is repeatable.  Using the equivalent i386 ISO image, the
  issue does not occur.  Using the Lubuntu 12.04 amd64 ISO image, the
  issue also does not occur.

  If one enters a suitable IP (I used 8.8.8.8), the installation
  continues but when booting into the new (virtual) machine, DNS is not
  functional and /etc/resolv.conf does not contain the expected

  nameserver 8.8.8.8

  line, but instead contains

  nameserver 127.0.0.1

  Workaround:

  Hand editing of /etc/resolv.conf fixes this at least temporarily, and
  editing /etc/network/interfaces fixes it more permanently, but clearly
  should not be necessary.
