The network service of Ubuntu system and this version of the network manager incompatible problem solving method

Or the hands of cheap, in the modified network configuration and update, boot, the machine has a wireless network card, wired network card is also very strange, must restart network to be able to even go out.

When you open the Network connection panel for the system, an error occurs that the network service of the system is incompatible with this version of the network manager.

Using the almighty Google, found a solution. Method is more inconceivable, I anyway wood have understand, but it became ...

The method is 4 steps, look at the following reference:

The code is as follows:

The Terminal and log in as root.

# su

After this go the correct folder.

# cd/etc/networkmanager/system-connections/

Now take a on the content of this folder. If you had a VPN connection e.g. there must is a file with the name of that connection.

# Ls-la

Now and can remove that file or you can move it to another folder (so and can set it back if this solution does not work F or your problem).

To move the "file to your Personal" folder use the following command:

# MV /home/ /#username是你的用户名

Now the "only thing" is starting the network Manager:

# NetworkManager

When ~ ~ ~ your network management interface appeared in the Long-lost wireless card ~lol

PS: There may be no configuration, please reboot
