Fingerprint GUI not installing in Ubuntu 20.04

Question

I'm trying to install fingerprint-gui on my Lenovo Ideapad 520 having Ubuntu 20.04 on which fingerprint isn't working for now.

I tried going directly to Settings → Users → Automatic login and enabled the fingerprint login, but the error is:

Could not access any fingerprint readers Please contact your system administrator for help!

I also tried to install Fingerprint GUI:

sudo apt-add-repository ppa:fingerprint/fingerprint-gui && sudo apt-get update 
sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

but encountered this error:

E: Package 'policykit-1-fingerprint-gui' has no installation candidate
E: Package 'fingerprint-gui' has no installation candidate

What could be the problem here?

Thee was never `fingerprint-gui` package in Ubuntu repos. You probably installed it from some PPA. — Pilot6, Apr 26 '20 at 11:55
Fingerprint GUI is no longer maintained and is not compatible with Ubuntu 20.04 and newer — sarru1291, May 27 '20 at 03:06

Follow this guide for non GNOME remixes:

https://ubuntu-mate.community/t/fingerprint-login-ubuntu-mate/20852

Fingerprint login setup is available via a GUI for Gnome, however there is no current GUI for Ubuntu MATE.

The following steps will enable Fingerprint Login and user privilege escalation in Ubuntu MATE, please note that some of this will be dependent on the specific laptop you are using.

First step check your laptop for an available fingerprint reader

lsusb

If you have one listed then please follow the steps few steps:

sudo apt install fprintd libpam-fprintd

Now you need to enroll your fingerprint:

fprintd-enroll

Follow the prompt and swipe your right index finger across your scanner 5 times until you get the following: Enroll result: enroll-completed

Now you need to enable access:

sudo pam-auth-update

This will open an ncurses interface. Add an * next to Fingerprint authenication and tab over to OK and exit.

At this point you will be able to use your fingerprint scanner to authenticate to elevated privileges, ie. sudo. It will also allow you to login and unlock your system using the fingerprint reader.

This has been tested on Ubuntu MATE 18.04, 19.10, and the current daily 20.04.

(Also I can confirm Xubuntu 20.04.)

thanks, I think running pam-auth-update and enabling fingerprint made my Goodix fingerprint reader work on my Dell Inspiron 5482 after following : https://www.reddit.com/r/Dell/comments/hq3kf3/xps_13_fingerprint_drivers_are_here/ :) — Vincent Gerris, Jul 30 '20 at 12:43

Fingerprint GUI is no longer maintained and is not compatible with Ubuntu 20.04 and newer. There is a built-in fingerprint login feature in 20.04 under Settings->Users->Authentication & Login.

You may need to add the drivers for that particular reader. – Alan Brooks May 05 '20 at 21:22
What about Xubuntu? – fleamour May 20 '20 at 12:04
@AlanBrooks , By any chance, Do you know what drivers do I need for an Asus Laptop for enabling fingerprint scanner? – Jdeep Aug 25 '20 at 16:37
It depends on which scanner you're using. If it's built-in, then I'd check the Asus website. – Alan Brooks Aug 26 '20 at 18:55
nothing like fingerprint feature for Lenovo P50 available even in Ubuntu 20.10 – mirec Dec 28 '20 at 23:07
There is no such settings on my Lenovo laptop with built-in fingerprint reader. – Yanick Rochon Jan 02 '21 at 02:07
Tested on Ubuntu 20.04 LTS and on Lenovo ThinkPad T590. OK. – Rudy Vissers May 03 '21 at 08:42

You need to add the PPA first.

sudo add-apt-repository ppa:fingerprint/fingerprint-gui

Luckily it already supports focal.

I did add the PPA first, and then I installed libbsapi policykit-1-fingerprint-gui fingerprint-gui. And it gave me this error – Prince Kukreja Apr 26 '20 at 17:08

except it kinda doesnt its build for focal is having a dependency wait for libpolkit-qt-1-dev which straight up is as far as I saw not being built for focal. – My1 May 04 '20 at 20:10
