MarsSeed [1] filed a deletion request for fingerprint-gui [2]: EOL since 2017; not compatible with fingerprint reader devices produced during the last 5 years, as it depends on the deprecated libfprint-1 (which fails to build in clean chroot).
Not useful to keep; there are better alternatives. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/fingerprint-gui/
