Binary package “connman-ui” in ubuntu cosmic

full-featured GTK-based tray icon UI for ConnMan

 ConnMan-UI targets all WM/DM users except those running Gnome3. It works
 on any Linux WM/DM which provides a freedesktop-compliant system tray.
 (KDE, awesome, i3, Xfce, ...)
 .
 It exposes almost all features provided by the ConnMan API. You can:
 .
  * enable/disable a technology (wired, wifi, cellular, bt, ...),
  * connect/disconnect a service
  * configure a service (IPv4, IPv6, DNS, timeservers, etc...)
  * share your current connection (tethering)
 .
 Everything is accessible through the mouse via the system tray icon using
 left/right click.
