I always used to be able to do
Password: (I enter the root password here)
After the upgrade from Fedora 14 x86_64 to Fedora 16 I get:
Password (I enter the root password here)
su: incorrect password
Worse, before displaying "Password" in the new tab I now get a popup that says:
Privileges are required to enroll new fingerprints for other
An application is attempting to perform an action that requires
privileges. Authentication as the super user is required to
perform this action.
The computer is a Thinkpad that does have a fingerprint reader. But I have always ignored the fingerprint reader. I wonder if the upgrade from Fedora 14 to Fedora 16 helpfully decided to enable the fingerprint reader. But even if it did, why would it be called upon when I try to become root at the command line?
Note that sudo still works, and so does sudo su, and neither causes the popup window to appear. Does anyone know what is going on and how to fix it?
