system network services are not compatible with this version

[hopefulp]

Hello,
Yesterday, the system informed that there were updates with some options of "update now, later..."
So I closed all the panes and updated.
Then reboot, but the network is completely gone.
In the menu bar, there is no icon for network.
And through setting, network -> it shows just network proxy and the error message of the title: system network services are not compatible with this version.

I can easily find the remedy for Ubuntu, there there is no helpful information for debian.
I am using debian 8.5.

It looks like bug. Would you help this issue?

Panes? I don't know about "the panes" but it isn't necessary to close all the panels before updating. I seem to remember that's necessary in Windows though but maybe things have moved on since I used Windows95.

Then reboot, but the network is completely gone.

In the menu bar, there is no icon for network.
