This question already has an answer here:
I am running 14.04 LTS on a Dell XPS 13 9343. Today I did a routine update through Software Updater and restarted when it prompted me. When I logged back in I had no internet connection and no icon in the menu bar to edit connections. When I open "Network" within the main Settings menu, I get the message:
The system network services are not compatible with this version
When I open the "Network Connections" dialog, all options are greyed out. I have attempted to connect to Ethernet as well as WiFi to no avail.
Please help, I am freaking out. This is the machine I use for my job and doing a fresh install of Ubuntu would be a massive hassle as I have all kinds of specialized software packages installed.
I should also mention that I tried reinstalling
network-manager. I even removed and purged it, then reinstalled from the package provided on the Ubuntu website. That didn't change anything. I also purged and reinstalled the network-manager-gnome package to see if I could fix the GUI issues (
nm-applet not working) but that didn't do anything either.
