Package: xfce4-session Version: 4.20.0-1 xfce 4.20 xflock4 utility uses a gdbus call to assert the lock screen utility.
By default, xfce4-session 4.20.0-1 is missing the dependency, rendering screen lockers like xfce4-screensaver, light-locker, etc not working.
Installing libglib2.0-bin fixes the issue, since it provides gdbus utility. Please consider adding libglib2.0-bin as a dependency to xfce4-session. Thanks!
