In systemsettings when setting up the fingerprint for a user, it didnt do anything. Normally there would be an interactive setup, with the turning circle etc. It seemed to not work. kcm_ufprintd-enroll in terminal works normally, and actually told me the right-index-finger was already enrolled. So I assume this is only a KDE bug?

also even though set up successfully, it does not yet work on the lock screen. this may just be because of the user not having logged out and in again
I'm afraid you're going to have to be a lot more specific than "it didnt do anything." Can you open `systemsettings kcm_users` in a terminal window, and then tile the terminal window to one side of the screen and the System Settings window to the other, and then attach a full screen screen recording of yourself enrolling your finger that shows the issue happening as well as the log output in the terminal window throughout the process? The lock screen issue is likely due to a local PAM misconfiguration; see https://community.kde.org/Plasma/Plasma_6.0_Release_notes#New_required_PAM_configuration

The right thumb is now shown as registered in the systemsettings GUI, but the left index finger which gave an error is not shown. This may be a libfprint bug. I also already tried to delete the fingerprint earlier. fprintd-delete * found 1 devices Device at /net/reactivated/Fprint/Device/0 Using device /net/reactivated/Fprint/Device/0 No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors No fingerprints to delete on Synaptics Sensors
I was also able to completely normally register a different finger through the GUI, I think this is just systemsettings reacting because libfprint is not reacting. Now after this seemingly resultless fprintd-delete I open systemsettings again in the user section and it is still showing the entries. I cannot use the fingerprints in pkexec and sudo though.
So both the GUI and CLI fail to enroll your left index finger, but both succeed at enrolling all other fingers? Do I have that right?
No, I assume this is purely an fprintd bug and not KDE related setting up 2 different fingers through the GUI worked normally, but even the CLI didnt allow to remove that zombie default right index finger. I will close this bug for now as "upstream" and link it to Fedora Bugzilla
