fprintd-enroll error

Installed fprint following wiki insturctions, upon attempting step 3.2 it gives me an error.

$ fprintd-enroll
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-duplicate

Ive tried using

 $ fprintd-delete "$USER"

However it has made no effect.

Re: fprintd-enroll error

Fixed it by

 sudo rm -r /var/lib/fprint/

Ive registered, however it still won't let me use my fingerprint in place of my password.

Re: fprintd-enroll error

Did you configure PAM?

If you added...

auth        sufficient      pam_unix.so try_first_pass likeauth nullok
auth        sufficient      pam_fprintd.so

...to one of the mentioned files in /etc/pam.d, then you must first press enter to skip the password request, before you can use the fingerprint reader.

I got both fprint and howdy to work with Lightdm just following the wiki, so the info you need should be in there
(In the end I removed them again, because I find it easier to just use the password - so I'm afraid I can't share my actual configuration)

EDIT: I may have been a bit quick there; I remember installing fprintd-vfs_proprietary from the AUR, due to compatibility issues with my fingerprint sensor. Might be worth checking out. There's some talk on the AUR package page, and also there's more packages like that in the AUR.
Also check: https://fprint.freedesktop.org/ and https://linux-hardware.org/?device_type … int+reader

I got it working on sudo and lightDM (on switch user screen) however the lock screen still does not accept fprint.
