I have a computer on Ubuntu 18.04 (actually upgraded from Ubuntu Gnome 16.04). I need to set up screen sharing but the option isn't there.
In settings > sharing, the master sharing switch is on and I see computer name, but underneath that only Remote login and File sharing - no option for screen sharing as the docs suggest it should be.
As per the title, vino is installed - maybe there's another package I need that somehow didn't transition between the two versions?
