Enroll fails on Thinkpad P51 (138a:0097), Linux Mint #268
Description
Laptop: Lenovo Thinkpad P51
System: Linux Mint 22.3
Fingerprint-Reader: Bus 001 Device 003: ID 138a:0097 Validity Sensors, Inc.
All the steps in "Setting Up" worked fine, until I got to $ fprintd-enroll. The light above the fingerprint reader lights up; When I place my finger on it and lift it, the stage gets passed, but in the end the enroll fails:
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-stage-passed

Enroll result: enroll-stage-passed

Enroll result: enroll-failed
I have tried many times but always get the same result and I couldn't find any issue that seemed to solve this.
The following is the result from $ sudo systemctl status python3-validity:

Does anyone have an idea what the issue might be or how I can find out?
I'd very much appreciate any help! :)

@Jakeory1 have you tried to specify finger on
fprintd-enroll? From error it seems like it tries to write finger over already existed one. E.g. try to usefprintd-enroll -f left-index-finger
