Ubuntu 12.04 & quot; the network service of the system is not compatible with the network manager of this version.

The Network Service of the ubuntu 12.04 system is not compatible with the network manager of this version. This morning, I had a mess in the lab and did not know what the problem was. As a result, after the restart, the Network Map icon was unavailable, miserable drama. When www.2cto.com starts the system settings-"network, the result shows that" the network service of the system is incompatible with the network manager of this version ". After checking the information, the problem is solved, here mark 1 su2 cd/etc/NetworkManager/3 rm system-connections4 mkdir/system-connections can move the folder in step 1 elsewhere for recovery if you are afraid of poor processing. Restart NetworkManager and your network connection will come out! 1 NetworkManager
