I finally had a chance to try this out and I followed @Ian_Cleary’s instructions and got the lib and the daemon to build without issues. However, fprintd doesn’t seem to be working correctly. Checking my user account in the Gnome settings shows me a grayed out option for fingerprint logins which disappears entirely after about 30 seconds. Running fprintd-enroll directly gives me an error after 25 seconds saying that it couldn’t connect to the service and timed out. Systemctl says that the fprintd module loaded, then immediately errored out, but I can’t tell what the underlying error was (“failed with result: ‘exit-code’”). The only thing that might be a useful error was the line “undefined symbol: fp_device_has_feature, version LIBFPRINT_2.0.0” which doesn’t give very meaningful results in Google. Any ideas?
I was able to get a fingerprint enrolled on Ubuntu 21.04 using the most recent instructions from Ian, except I had to also install libsystemd-dev and I had to add the install command at the end of the ninja commands so that libfprint and fprintd would get installed to /usr/local/
Specifically,
sudo apt install libsystemd-dev
and then for libfprint and fprintd:
ninja -C builddir install
Then, fprintd-enroll worked.
Have you figured anything out on this? I got myself into the same situation, same finger even. There is a “Clear TPM” checkbox in the BIOS Security screen, but it does not reset the fingerprint.
No, but I think the Framework folks are looking into it.
Okay, I tried building everything again from scratch, adding in @Ryan_Helinski’s comment about libsystemd-dev and this time watching the meson build output. I noticed during the build of libfprint that it seemed to be missing a reference to the Cairo graphics library, so I also added
sudo apt install libcairo-dev
as well. Built libfprint, built fprintd, and everything seems to be working as expected now.
@R_L_Royall_Jr I also found that I did not have to install libfprint-2-dev. I have since also learned that other instructions recommend that you first remove the older, system-provided libfprint and fprintd with the command:
sudo apt purge --auto-remove fprintd libfprint-2-2
The new fprintd-* commands will still work with the system-provided software installed, but you might as well save some space and possible contention / confusion.
I am having what looks like the same problem as some others have reported. I had successfully enrolled my right index finger and middle finger fingerprints on my first Fedora 34 respin install a few days ago. I reinstalled the exact same respin and got the error “Failed to enroll new fingerprint”. I was able to enroll some other fingerprints, so appears as if something is not cleared out on install. I repeated the experience with the respin that just came out today, August 16. After the successful enroll of a different fingerprint, I saw that a button for something like “Delete Fingerprints” appeared, so I tried that, hoping it would clear out the data that seems to be preventing me from being able to register my index or middle fingers on this fresh install. (edit: It did not resolve the problem.)
dnf info libfprint says I’ve got the following installed:
Version : 1.90.7
Release : 3.fc34
I’ve solved the issue of the fingerprint option disappearing in Fedora34/Gnome40!
Found the solution here: https://www.reddit.com/r/Fedora/comments/oik8sq/need_help_setting_up_fingerprint_auth_in_fedora_34/h4xvrqv
In short, these three commands brought it back in the UI (though I still have no idea why it disappeared in the first place - something I did while troubleshooting fprintd)
$ sudo authselect current
$ sudo authselect enable-feature with-fingerprint
$ sudo authselect apply-changes
Note - this doesn’t fix any issues with fprintd or the fingerprint reader itself. At this point, I had verified that fprintd-enroll was working perfectly, I just didn’t have the UI integration piece working.
On Ubuntu 21.04, I just installed libfprint and fprintd v1.94.0 following a slightly modified version of @Ian_Cleary 's instructions. Instead of sudo pip install I installed python packages in a virtual environment. It worked no problem for libfprint 1.94.0. When installing fprintd, however, I was stuck with this error message, even though I had installed the dependencies including python3-pypamtest:
meson.build:134:8: ERROR: Problem encountered: Python3 module 'pypamtest' required by test suite not found
My workaround was to comment out this line in meson.build:
'pypamtest': get_option('pam')
Has anyone succeeded in using fingerprint for things other than the login screen? e.g. sudo on the terminal, or other dialog boxes that ask for authentication?
@Atul_Ingle my fingerprint works in terminal on the Respin of Fedora that Framework recommended.
@Atul_Ingle I use it to unlock 1Password, works perfectly. On first boot, I have to use my master password to unlock 1Password, but after that, I can just use my fingerprint.
UPDATE: Ooooh, I just noticed I can also use my fingerprint to sudo!
Oh. That is SLICK!
if anyone’s wondering, setting up the fingerprint to work with sudo is simple for Ubuntu 21.04. just need to run sudo pam-auth-update and use the spacebar to enable fingerprint auth. there’s a stackexchange on this as well sudo - Use fingerprint authentication not only for login - Ask Ubuntu.
obviously, you need to have built libfprintd with the directions laid out above and enrolled your fingerprint. for me, i needed @Ian_Cleary’s directions and @Ryan_Helinski’s addition of using install at the end of the ninja command. additionally, i had to use sudo to install ninja since meson was looking for it in usr/local/bin. i built the latest version from source which is libfprintd v1.94 i believe.
@garrett528 I don’t see a fingerprint option when I run sudo pam-auth-update. I think I may have to manually edit some files in /etc/pam.d/
I have this problem. It appears the fingerprint reader has storage of its own, and when fprintd can’t tell the fingerprint reader what fingerprint to delete, it can’t tell the reader to wipe its memory and start over.
We started a thread with the sensor maker to see if they have a solution for this.
I’m having an issue with building fprintd (v1.92.0) via meson builddir
meson.build:84:0: ERROR: Dependency "libfprint-2" not found, tried pkgconfig
but, libfprint (v1.92.1) build just fine.
in the log from the failed build of fprintd, I saw this error:

In another thread, I learned about ninja -C builddir install, which I ran in the libfprint directory.
And now I get a different error from fprintd meson builddir

Use Void Linux, where the binary package is at 1.94.0 
(shameless plug)
Well, I’m already using Ubuntu 21.04 – (and have a lot of setup scripts for ubuntu, so I think I’ll stick with that)
