Expected Results:  
Liveinst to start

Looks like the error started after anaconda changing from consolehelper to pkexec.

I managed to find one solution by adding xfce-polkit to our common Kickstart, and by adding this to our %post section at fedora-live-i3.ks:

cat > /etc/xdg/autostart/xfce-polkit.desktop <<EOF
[Desktop Entry]
Type=Application
Name=xfce-polkit
Exec=/usr/libexec/xfce-polkit
EOF
