What have you tried:
Tried copying my xfce-screensaver.xml to /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/ and rerunning apt autoremove -y or dpkg --configure -a and get told permission denied.
Permissions and ownership on xfce-screensaver.xml are the same as all others.
What is the error:
Initial error after full-upgrade is

After copying my xfce-screensaver.xml to the /etc location it is

What device is this on:
VMWare Player virtual machine. First time I have encountered this after any earlier full-upgrade in a couple of years. Note, this is one VM I user regularly, while other I blow away once they are done.
