** Description changed: After upgrading ubuntu desktop from 19.10 to 20.04, it's impossible to enable screen sharing. It used to work fine on 19.10. When clicking the enable/disable toggle, the following message is logged in journalctl: Failed to enable service vino-server: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Sharing cannot be enabled on this network, status is '0' This is reproducible on both computers I've upgraded. They're both on the latest 20.04 package updates as of today.
