Please quote the exact error message (in English as well). Looks like
the PAM stack is badly configured.

You're mixing bits from fprintd (including its pam_fprintd PAM module),
and pam_fprint, which is completely obsolete software. fprintd-enroll is
the correct command for this.

I have no idea why your PAM configuration would ask for the password
first, but it's clear that you should look in that direction for solving
the problem.
