[Bug 856810] Re: Boot hangs at "Booting system without full network configuration..."

[Sebastien Bacher]

the issue there doesn't seem to be lightdm, if you have an issue due to
the default-display-manager, use #864174

Title:
  Boot hangs at "Booting system without full network configuration..."

Status in “lightdm” package in Ubuntu:
  Invalid
Status in “netcfg” package in Ubuntu:
  Confirmed

Bug description:
  I installed Ubuntu 11.10 beta1 64bit on a new laptop. I rebooted and
  it came up nicely.

  After that I did "apt-get update" and "apt-get dist-upgrade" to get
  the most recent fixes and installed some additional software.

  Now I do not seem to be able to boot.

  Fist I see:
  Waiting for network configuration...

  Then I see:
  Waiting up to 60 more seconds for network configuration...

  And then it just hangs forever displaying the following:
  Booting system without full network configuration...

  Nothing happens after that, no matter how long I wait. However, I can
  switch to the console with CTRL-ALT-F1 and log in from there. The
  network is configured with DHCP and it works just fine from the
  console. I do not understand what the GUI boot display is waiting for.

  I installed the system using the alternate install CD to get LVM based
  partitions with full disk encryption.

  I noticed the bug #847782 and removed the "auto eth0" entry from my
  /etc/network/interfaces. Unfortunately that did not change anything,
  it still hangs forever.
