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  • Fingerprint GUI is no longer maintained and is not compatible with Ubuntu 20.04 and newer – sarru1291 May 27 '20 at 3:06

Fingerprint GUI is no longer maintained and is not compatible with Ubuntu 20.04 and newer.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 5 '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

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

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.)

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 4 '20 at 20:10

sudo pam-auth-update

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