sharing relies on network manager handling the connection

[Yannik]

It's impossible to enable screen sharing when systemd-networkd is used as netplan renderer.
The following message is logged in journalctl when trying to enable screen sharing in the settings:

Failed to enable service vino-server: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Sharing cannot be enabled on this network, status is '0'

The happens when a connection is managed by systemd-networkd instead of NetworkManager:

$ networkctl
IDX LINK TYPE OPERATIONAL SETUP
  1 lo loopback carrier unmanaged
  2 enp1s0 ether routable configured

$ nmcli d status
DEVICE TYPE STATE CONNECTION
enp1s0 ethernet unmanaged --
lo loopback unmanaged --

Thank you for your bug report, that's an upstream issue and ideally should be sent to them on https://gitlab.gnome.org/GNOME/gnome-control-center/issues if you could do that?

GNOME currently relies on network-manager, it wouldn't be surprising if other settings panel don't handle well networkd being used instead (the network one for example)
