This problem happens sometimes when ubuntu starts up. You can't really boot to the interface sometimes.

Splash Screen with the 5 dots and a message saying:

waiting for network configuration then:

waiting an additional 60 seconds for network configuration

I decided to go the CLI and Alt+Ctrl+F2 approach so YOU ARE FREE to do that while you are logged in to the GUI - Okay, I will write the general steps so feel free to use whatever approach you like.

  1. Edit /etc/network/interfaces:

    sudo nano /etc/network/interfaces
    

1.1 If you are typing this from LXTerminal while logged in to the GUI then:

gksudo leafpad /etc/network/interfaces
  1. Remove whatever written there and just keep this:

    auto lo
    iface lo inet loopback
    

It is very good idea to keep a backup copy of "interfaces" file just in case so please make sure to save a "interfaces.bak" file before you do anything

  1. Ctrl + O if you are using nano and Ctrl + S (File > Save) if you are using leafpad.

  2. Ctrl + X if you are using nano and Ctrl + Q (File > Quit) if you are using leafpad.

  3. Reboot.

  4. Done.

auto lo iface lo inet loopback doesn't work –  draw Mar 7 '13 at 17:11
    
@draw it has to be on two lines: 1st line is auto lo; 2nd line is iface lo inet loopback –  daniel kullmann May 27 '13 at 8:42

@danielkullmann ; auto lo; (1st line) iface lo inet loopback; (2nd line) It doesn't work for me either. I need to manually configure the interface and give its address !! –  cognoz Jun 27 '13 at 6:48

In every situation that I have run into this it is a problem in /etc/network/interfaces

You should not have to remove everything as suggested in an earlier post, but rather inspect for common problems.

In my case it was defining the gateway parameter for additional ethernet IPS. You only need to define the gateway for the primary interface for each card.

What I mean by this is if your file looks like this:

auto eth0
iface eth0 inet static
  address 10.0.0.5
  netmask 255.255.255.0
  network 10.0.0.0
  gateway 10.0.0.1

auto eth0:0
iface eth0:0 inet static
  address 10.0.0.6
  netmask 255.255.255.0
  network 10.0.0.0
  #gateway 10.0.0.1

The 2nd gateway param will cause ubuntu to hang for 60+ secs during boot, you only need to define the gateway for the first eth0 section, you DO need to define the gateway for any additional nic cards, IE eth1, wlan0 etc but NOT for additional IPS assigned to the same nic. Earlier version of Ubuntu did not have any issues with this, but Ubuntu 12.04 does not like it... Be nice if it could simply ignore it.

I'm sure there are other "problems" in this file that can cause this, so you should inspect the file and make sure there are no typos etc.

The "network" option is obsolete, no longer needed. –  jdthood Mar 25 '13 at 11:29

this answer does not apply to me, I have no gateways in any active stanzas of this file –  memnoch_proxy Jul 23 '13 at 2:41

This might help too: http://tech.pedersen-live.com/2012/05/disable-waiting-for-network-configuration-messages-on-ubuntu-boot/

Basically you edit this /etc/init/failsafe.conf file and disable (comment) the sleep commands which actually pause the system. Besides accomplishing the job, at least in my case there was no error at all in the network configuration, so everything went fine.

By the way, you solution only allows to configure the loopback interface, something I could not afford in my setup (I had to manually setup the interfaces and bridges).

Add a # in the /etc/init/failsafe.conf file in front of all lines containing sleep <n>. Doing so would help to boot fast.

Could some of those lines (and the deliberate delays they produce) be important? If not, I recommend expanding this answer to explain why. –  Eliah Kagan Mar 25 '13 at 11:43
    
@aditya Commenting Sleep only enables faster boot. But the real problem is that the network manager doesn't start. So how to solve that ?? –  cognoz Jun 27 '13 at 7:08
    
@Krishna: I didn't answer this question, I had just edited it for proper formatting; hence don't have any idea how to solve your problem. It would be preferable if you ask a new question. Provide a link to this question if it helps. –  Aditya Jun 27 '13 at 14:37
    
@Aditya ok thanks. I have somehow managed to get it solved. I am not fully satisfied with the network-manager, but I can ping and connect to network now. –  cognoz Jun 28 '13 at 20:03
