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. I've done some research to rule out common faults: $ cat /etc/netplan/01-network-manager-all.yaml # Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager (Yes, I've ofc ran netplan apply, but the file already had this content anyway.) $ cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no Also, this seems unrelated to #1871787: $ dpkg -l |grep gnome-settings-daemon ii gnome-settings-daemon 3.36.0-1ubuntu2 ii gnome-settings-daemon-common 3.36.0-1ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1876884/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
