Hello together. I searched but could not find recent updates to the current status of the fingerprint function in this forum.
I am running a debian bookworm alpha installation (5.19.0-2) and installed fprintd and libpam-fprintd, both version 1.94.2-2.
I am able to start the enrolment after installation via command line, and everything seems fine. However after activating libpam-auth, testing with e.g. sudo -k && sudo -i doesnt ask for a fingerprint, only password. When trying to re-enrol or enrol a different finger, the process finishes with “an unknown error has occured”.
The same issue when purging all packages and trying to enrol via the KDE system settings.
I ran into this issue when distro hopping when I first got my framework, tracked it down to my fingerprint being remembered by the device, but not the OS. If you enrolled a finger, but cant do it again, it might be this. In this thread there is a script you can use to wipe the reader memory and try again. I hope it works for you, I had a hard time getting the reader to work in anything until the distro included supported for it.
