Since libnm-glib will be removed in 19.10, I have ported the network panel from g-c-c 3.26.
How to test:
Add the ppa
sudo add-apt-repository ppa:unity7maintainers/unity7-desktop sudo apt-get update sudo apt-get install unity-control-center libunity-control-center1 unity-settings-daemon libunity-settings-daemon1
Reboot. Go to unity-control-center->network, check if everything is working.
Note: If you vpn/vlan or ip-tunnel, there is NO gui in network panel (as g-c-c doesn’t have gui yet), in that case just use
nm-connection-editor from unity panel.
