Comment 15 for bug 1789097

As a workaround, could you try creating this file: /usr/lib/networkd-dispatcher/routable.d/10-winbind

with these contents:

#!/bin/sh

pid=$(systemctl show winbind -p MainPID --value)
if [ "$pid" -ne "0" ]; then
    kill -HUP $pid
fi

Then make it executable: sudo chmod +x /usr/lib/networkd-dispatcher/routable.d/10-winbind

That's assuming you have the networkd-dispatcher package installed. It's not mandatory, but likely that you have it. If you don't, then please install it.
