Fingerprint GUI not installing in Ubuntu 20.04

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?

Follow this guide for non GNOME remixes:

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

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.)

Fingerprint GUI is no longer maintained and is not compatible with Ubuntu 20.04 and newer.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 need to add the PPA first.

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

Luckily it already supports focal.

sudo pam-auth-update

works fine with standard (not tuned) U20.04.2 finally I can confirm sudo actions via fprint reader
