[Alex Mandel]

Also just happened to me on a machine with "proposed" disabled. I fixed
by downloading a newer version of network-manager via another
computer/usb stick. My system seemed to show a newer version was
available, and had I done the upgrade before turning it off it probably
would have skipped this issue.

http://packages.ubuntu.com/trusty-updates/network-manager

I also grabbed libnm-glib4_0.9.8.8-0ubuntu7.3_amd64.deb and libnm-
util2_0.9.8.8-0ubuntu7.3_amd64.deb as I wasn't sure if they were needed
to fix the problem or required by network manager.

[Tom Dalton]

My Ubuntu 14.04 laptop downloaded these 3 3.2.21-1ubuntu1 packages on
Friday 13th May, and after a restart my network manager was unable to
start (segfaulting presumably for the same reasons as original).

Downgrading to the previously-installed -1 packages worked for me.

Happy to provide any more info requested.

[David Strausz]

Received 3.2.21-1ubuntu1.1 versions of libnl* with upgrade about a day
ago, even though definitely have "proposed" repository turned off.  This
cause network-manager to fail after boot, as described.

Recovered by manual downgrade of libnl* as described
(http://askubuntu.com/a/727462).

Then upgraded again when internet connection restored.  This re upgraded
the libnl* packages to the 3.2.21-1ubuntu1.1 versions again, but also
upgraded network-manager to 0.9.8.8-0ubuntu7.3 (it was previously vrs.
7.2).  Everything works again with these versions.

[Vasiliy Pedak]

I've managed to make all working by such steps
http://askubuntu.com/a/727462 - manual downloading and installing
packages. Except adding the freshest libnl* packages on hold. So after
manual downgrading and restarting `network-manager` I got network
working. Then I did

sudo apt-get update
sudo apt-get upgrade

Everything works now.

As of yesterday I had no internet connection (updates where performed on 14.04 
without proposed updates enabled).
Thanks Matthias, your comments did the trick for me too, internet is back (just 
had to restart the network-manager afterwards):

sudo ifconfig wlan0 up
sudo ifconfig eth0 up
sudo dhclient

sudo apt-get update
sudo apt-get upgrade

sudo service network-manager restart

This hit me 1 hour ago after i had a pwer down because i forgot to link
the power cable. After reboot i had no network at all. I had no symbol
in the header bar. "rfkill list all" shows all blocked. manually
starting "service network-manager restart" not wirked with an exception.
After searching alsmost one hour for the problem i looked in

> cat /var/log/syslog

and search then for the logged error in google with

ubuntu networkmanager general protection

this bug. Now with

> ifconfig wlan0 up

and

> ifconfig eth0 up

and

> dhclient

it worked. Then i did an

> apt-get update and apt-get upgrade

while that the networkmanager comes back to life and the symbol comes
back to life.

As from yesterday it seems this update was moved from purposed to updates, so 
it will happen to anyone updating 14.04 LTS . 
So it's highly important to bundle the network-manager update to this 
libnl-updates IN ONE STEP. (a job for canonical here ;) ). 

All or nothing should be the right way to  keep customers or users away
from this problem.

[castlehard]

-> manually updated network-manager to the 7.3 Version:
# sudo apt-get install network-manager
and did an unhold of the libnl-* packages, started update-manager (did an 
update to these libnl things) and rebooted as wanted by the update-manager.

Everything works fine now.

[castlehard]

Seems like a "This bug was fixed in the package network-manager -
0.9.8.8-0ubuntu7.3" problem.

Same at my place, no proposal repository activated.

My network-manager still is the "old" 0.9.8.8-0ubuntu7.2. So it seems
for me like the update of the network-manager did not make it into the
"yesterday's patchset", and now we are a bit offline.

So: update the patchset-list to make both changes happen the same time.
I think this would solve all the problems with this bug.

After 40 hours of trying, I bought a DVD reader and reinstalled Ubuntu. 
I encourage to implement: when we accept proposed updates, a warning appears 
explaining the risks.
Reason: many of us can not understand what is suggested here or elsewhere in 
Internet related with Terminal -no further than copy even if we have an 
extra computer to read online the suggestions -Network Manager was broken- and 
try to solve this problem for days, we still can not repair this bugs. 
PS: move/copy this suggestion if you think of a better place for implementation.

Same same problem

Following suggestion of comment #27 bug #1539513

I restored network with:

:# ip link set dev eth0 up
:# ip addr add 192.168.x.z/24 dev eth0
:# ip route add default via 192.168.x.y dev eth0
:# echo nameserver 192.168.x.y >> /etc/resolve.conf

 and than updated NetworkManarger to proposed version 0.9.8.8-0ubuntu7.3 via 
synaptic
no downgrade of libnl.

Solved for me

[Bug 1539634] Re: network-manager crashes when using libnl-3-200-3.21.1-1ubuntu1

[Samuel]

How did you fix it? I assume that I have to go to 
"https://launchpad.net/ubuntu/+source/network-manager/0.9.8.8-0ubuntu7.3; and 
to "Downloads" where there are 2 folders and one file. If that is right, what 
should I do with those and how can I install them? 
Thank you!

Kubuntu 14.04 user here. After updating network manager and libnl*
packages, ethernet came back but can not enable wireless. Had to
downgrade the 3 libnl* packages again for the wireless settings to
reappear.

Unfortunately, I have found that it did not work for me.

I first tried a standard apt-get upgrade (in which I noticed a new
network-manager package) and rebooted, to find no real change - network-
manager still SEGVs.

Then I tried downgrading libnl-3 (as described above) and rebooted.
Again, no change - network-manager still SEGVs.

[Ryan Harper]

Correct.  We pushed the nm fix so anyone using trusty-proposed would be
fixed but the libnl fix needs more time to test.  Only users who have
trusty-proposed are affected and this fixes that while we do further
validation on libnl dependent applications for regressions.

[Blacky Bones]

I have been following this since Saturday night after installing the
update.  I was able to connect to the Ethernet with the workaround #7.

 I just installed the latest update from the Software Updater and it
boots fine.  I still get a system error message, but the Internet works.

The internet icon is now active, but when I disconnect from the
Ethernet, it shows that it is disconnected, BUT I am still connected.

Don't know if this helps.

I did remove the workaround #7  wicd-gtk

[Stéphane Graber]

Hello Ryan, or anyone else affected,

Accepted network-manager into trusty-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/network-
manager/0.9.8.8-0ubuntu7.3 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

+ 
+  * NetworkManager is a highly visible package, so testing NetworkManager

+ 
+ [Original Description]
  Testing out proposed libnl-3 package[1] exposed a bug in NM 0.98.
  
  After installing updated libnl3 and restarting networkmanager, NM
  crashes with:
  
  /var/log/syslog shows:
  init: network-manager main process (1057) killed by SEGV signal
  init: network-manager main process ended, respawning
  init: network-manager main process (1065) killed by SEGV signal
  init: network-manager respawning too fast, stopped

+ [Triage Notes]

+ This regression is caused by a libnl proposed update tracked in bug

+ 
+ If you are not aware that you volunteered to test proposed updates, then

Managed to bring Internet back by using:

sudo ifconfig eth0 up
sudo dhclient

But I cannot downgrade:

sudo apt-get install libnl-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1 
libnl-route-3-200=3.2.21-1

[Bug 1539634] Re: network-manager crashes when using libnl-3-200-3.21.1-1ubuntu1

[Samuel]

Downgrading using the terminal needs internet in our machine. And if we
paste the previous libnl with a USB stick and click, Ubuntu Software
Center says -Error. A later version is already installed-. I tried
desperate many more things. Provably only a new repaired libnl UPDATE
which we can open by clicking might really solve this for everyone. I
believe there are more people affected but reporting this bug requires
internet.

Thank you.

[Bug 1539634] Re: network-manager crashes when using libnl-3-200-3.21.1-1ubuntu1

[Ryan Harper]

Hi,

For now, you'll need to downgrade your libnl-3 packages:

% apt-get install libnl-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1 libnl-
route-3-200=3.2.21-1

And you may need to apply a hold until a fix for NetworkManager can be
released.

% sudo apt-mark hold libnl-3-200 libnl-genl-3-200 libnl-route-3-200

And after the fix:

% sudo apt-mark auto libnl-3-200 libnl-genl-3-200 libnl-route-3-200

Confirm the bug in ubuntu 14.04 proposed updates.

 A workaround is to install the program wicd-gtk or to downgrade some
libraries as suggested.

It is a bad bug since your connection to the web becomes impossible. To
surf in the web and see this bug I used the bluetooth connection of my
smartphone.

[HugoHirsch]

Is it possible to somehow block libnl-updates until the network-manager
fix is available as well?

Otherwise people are going to run into networkless systems as reported in 
#1539513
Since 14.04 is a LTS this is rather risky indeed.

Yep, already have ran into that problem - rebooted and had no internet
due to NM repeatedly crashing. This is a severe issue.

I applied the two upstream commits into NM 0.98;  built the package and
it does fix the libnl-3 updated issue.  NM no longer crashes when using
the updated (proposed) libnl-3.
