This where the steps:
1 Installed a xubuntu VM
2 apt upgrade, dist-upgrade & reboot
3 installed ulatencyd & reboot
4 /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 does not start anymore and perm. problems start.
5 apt remove ulatencyd , autoremove & reboot
6 everything goes back to normal
