Title:
network-manager
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
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
Received 3.2.21-1ubuntu1.1 versions of libnl* with upgrade about a day
ago, even though definitely have "proposed" repository turned off. This

(http://askubuntu.com/a/727462).

I've managed to make all working by such steps

packages. Except adding the freshest libnl* packages on hold. So after
manual downgrading and restarting `network-manager` I got network
working. Then I did

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

All or nothing should be the right way

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

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

released.

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.
