Ubuntu – The system network services are not compatible with this version Ubuntu 14.04


I have Ubuntu 14.04 LTS installed on my PC. I have created some new accounts and then after I logged in to my own account there was no internet connection. When I try to open the network settings I faced this error

The system network services are not compatible with this version.

I have tried starting the NetworkManager manually with this command

sudo service network-manager start

but it has not worked.

Can you please help me?

Network Manager Crash on ubuntu 14.04

After upgrade from proposed repository the next packages: libnl-3-200, libnl-genl-3-200 and libnl-route-3-200.

You'll need to downgrade your libnl-3 packages:

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

if you can not install these packages or have trouble making the downgrade you can manually download them from here(from my account):



  1. Download the 3 files on another computer.
  2. Copy them to a flashdrive.
  3. Put the flashdrive in to the affected computer.
  4. Copy the 3 files into a new folder.
  5. Open a terminal in that folder and run

    sudo dpkg -i lib*.deb
    sudo reboot

    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
