Commonly we usually use a username with a password, a password or a code to block our equipment, although we currently have several other additional security resources implemented in our devices such as smartphone, tablet, laptop, desktop computer among others.
Although in many occasions they are not usually quite useful either due to the strength of the password or code, so during This latest generation has increased the use of biometric devices to replace these access credentials.
This time we are going to focus on one of the most popular biometric devices and currently in use in most of the latest generation mobile devices.
The fingerprint readerAlthough it is not specifically designed to be used as an access method, it is also used for other tasks such as logging in and out in a work environment, giving access, signing, among others.
Though In the case of Linux, the manufacturers of these devices do not usually offer their drivers.
So that for this problem we are going to talk about a utility what is going to support us with this fingerprint GUI which is an open source application to use the fingerprint reader on your system.
fingerprint GUI is a program that provides an interface and drivers for fingerprint readers. The package includes drivers from the open source fprint project as well as proprietary drivers not included in fprint.
How to install Fingerprint GUI on Ubuntu 18.04 and derivatives?
Si do you want to install this utility in your system to have a good support for your biometric device, we must first check if our device is compatible with the application.
Before starting I recommend disconnect all additional USB devices to your fingerprint reader, mouse and keyboard, this in order to effectively locate its ID in your system.
For this let's open a Ctrl + Alt + T terminal and execute the following command:
lsusb
When doing this, they should receive a response similar to this:
Now They should check from their displayed list if their device is compatible with the application, among the devices supported in it are:

If it is compatible, you can proceed with the installation, first We must add the repository to the system with this command:
sudo add-apt-repository ppa:fingerprint/fingerprint-gui
We update our list of repositories with:
sudo apt-get update
And now we must install the application along with some utilities for its perfect operation in our system:
sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui
We just have to wait for the download and installation to take place. When starting the application, we can start to register the fingerprints.
In addition, in case of handling more than one fingerprint reader, the application shows us a list in which we can select which one we want to work with and we select it to start the fingerprint registration with it.
How to uninstall Fingerprint GUi from Ubuntu and derivatives?
If you want to remove this application from your system They must execute the following commands, if they are using Ubuntu or a derivative with Gnome they must execute:
sudo apt-get install policykit-1-gnome
In the case of KDE, they simply have to replace by:
sudo apt-get install policykit-1-kde
Y finally we uninstall the application with this command:
sudo apt-get remove fingerprint-gui
And with that we will have already eliminated the application from our system.
This you describe, could be done for a long time; perhaps poking around a bit in the repos and pulling Github, what remains a pending issue is effective integration into the system, so that it can be used to log in, encrypt files, access applications, etc., which in my opinion is a shame, because it is already integrated by default in Android and in a good part of Windows ... 🙁
I have debian 10 and when it wants to validate the public key it throws me a message that says that there is no valid pgp data and then it does not find the packages when wanting to install, any clues about it?
