Ubuntu 12.04 Recent Update Breaks Network Services (FIXED)

[Melodie]

Hello,

I am using a system built on Ubuntu 12.04 Mini. I installed all xorg and xserver-xorg packages, all drivers, authentication packages and so forth. It's my 3rd or 4th install of the kind. I use Openbox as main environment, lightdm as session manager.

I arrived here after I searched the web for a 60 seconds delay to connection problem in my Ubuntu Precise box.

I first met with this bug report:
https://bugs.launchpad.net/ubuntu/+s...rt/+bug/881079

and I was frustrated because the Ubuntu version where it happens is the preceding one.

However I first had wicd-gtk installed and after I read the bug report I replaced it with network-manager. The problem was still there : 60 more seconds delay at boot and no network working once the desktop was on screen.

So I sought for the same error message on the web, but for Precise, and here I am after I found the present thread !

I have reinstalled the former packages as said in the first post of this thread.

Here are the packages I have in the Downloads directory:

-rw-rw-r-- 1 melodie melodie 85390 avril 12 2012 libnm-glib4_0.9.4.0-0ubuntu3_i386.deb
-rw-rw-r-- 1 melodie melodie 14226 avril 12 2012 libnm-glib-vpn1_0.9.4.0-0ubuntu3_i386.deb
-rw-rw-r-- 1 melodie melodie 135104 avril 12 2012 libnm-util2_0.9.4.0-0ubuntu3_i386.deb
-rw-rw-r-- 1 melodie melodie 527750 avril 12 2012 network-manager_0.9.4.0-0ubuntu3_i386.deb
-rw-rw-r-- 1 melodie melodie 1331728 avril 12 2012 network-manager-dbg_0.9.4.0-0ubuntu3_i386.deb

Just a hint : to download them with wget, it is not necessary to add one "wget" line for each package : they can be all added one after the other, with just a space separating each URL.

Another hint : provided you have only these deb files in the Download directory, or in another directory of your choice, you don't need to worry about the order in which you will install them if you invoke this command line:

sudo dpkg -i *.deb

dpkg will manage to install them all in the right order, always.

One last hint, for who wants to block the versions of these packages:
open Synaptic, find the package names with the search field, select them (Ctrl+click or Shift+click can allow selecting several at a time) and then go to menu "Packages" then hit "Block the version". You're done, now you should see a small icon looking like a lock in front of the names of the said packages.

After I installed the former version I rebooted and good surprise ! This time network manager was started !

But I still have a 60 seconds delay for network during boot, which I don't know why.

I connect with wired cable, on an Adsl connection, with the interface Eth1.

My Ethernet card is:

$ lspci | grep Ethernet
02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller
...

I won't quote my wireless card, as I didn't try it yet. (One problem at a time... right ?)

"sudo lshw" provides the information about the driver for this card:
e1000e

However, lspci seems to indicate that it is NOT used (?)

$ lsmod | grep e1000e
e1000e                139997  0

and to end with, here are a pair of additional informations:

$ ls -l /var/run/network
total 4
-rw-r--r-- 1 root root 6 nov.  18 15:45 ifstate
-rw-r--r-- 1 root root 0 nov.  18 15:45 ifup.eth1
-rw-r--r-- 1 root root 0 nov.  18 15:45 ifup.lo

and /var/log/boot.log:

I have looked into syslog messages too. I just installed libnss-mdns, which was missing and can help for some stuff. Since yesterday I have also added the following packages:
ifupdown-extra (0.22) (and re-installed ifupdown), gir1.2-networkmanager-1.0, (see the descriptions for each to see why I thought it could eventually help), and also installed libmtp-runtime (1.1.3-1ubuntu0.1) which was missing in my system and triggered and error message from dbus at the start of the boot (unrelated to the network problem, but any error message delaying the boot and solved is better).

I don't know if the driver e100e is used or not, and if not, what is used instead ? In the boot sequence I saw a line mentioning a virtual network : I don't know what it is about and if it is related in any way.

I will leave this post as is now, and will follow it, and seek for a related bug report on the Launchpad, if I can find one saying it happens in Pangolin Precise.

Thanks if anyone has any additional clue, links to other relevant bug reports...

@ drewski: I have marked this thread as 'Solved'. You can do this in future by clicking 'Thread Tools' and 'Mark this thread as solved.'

Thanks for pointing this out. I had the same problem, however a simpler solution worked for me.

First I checked whether network manager is working at all. Just type:

nmcli -f all -p nm status

Turns out, my NetworkManager was not running. This can be fixed easily by simply typing:

sudo NetworkManager

Voila! Hellooo internet!!

Excellent. Worked for me upgrading from 10.04.4 .

I also had 4 or 5 packages fail to install due to a password: prompt. I guess this is another topic.
