Maybe. If you have no other accounts other than the guest this bug is taking place ...

Yeah, you should get a root password request and it should just work.

There are some particularities to running such a privileged app in the guest session, it undoubtly needs a bit of work.

Maybe we can modify the policykit rule to allow the guest user to allow guest user to run the privileged operation, however would this cause potential security issue?

My problem is usb-creator doesn't work in Kubuntu 18.10. It fails to select the.iso file. Actually this problem is the same in the gnome version running on Kubuntu. Actually the two versions look very much the same, and have the same fault, which is it's impossible to create a USB stick with a distribution on it.
