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!

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
meson.build:148:8: ERROR: Problem encountered: Python3 module 'gi.repository.FPrint' required by test suite not found

Use Void Linux, where the binary package is at 1.94.0

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)
@NullVoxPopuli I saw both of those errors at one point.
#1 I think what fixed the libfprint-2 problem for me was sudo apt install libfprint-2-dev
#2 If you are certain that you installed all dependencies (in particular check for pip install gobject and pip install PyGObject), a hacky workaround would be to comment out the line in meson.build that says 'gi.repository.Fprint': true and then try again.
Hi all - an apologies for my lack of technical skills. Loving my Framework laptop and Ubuntu so far working SUPER well. I cannot seem to install the needed updates for the fingerprint reader - I am definitely NOT more the techy type and the chain of discussion is a bit hard for me. Any suggestions (other than the obvious: learn more about all this - hehe…) for a concise set of instructions for a total newbie? Or maybe the best recommendation is ‘wait til it gets rolled into Ubuntu itself…’

@Atul_Ingle you can edit /etc/pam.d/sudo to include the following lines in order to use fingerprint sensor first, and a password as fallback. Make sure that top line is at the top, as PAM reads sequentially line-by-line.

Thank you Anthony1, but I don’t know how to do what you are indicating. I am thinking the best answer for me it to just wait until its supported by Ubuntu. I know it seems very easy (and crazy that I don’t know how to edit using terminal, but it just seem to elude me without detailed instructions)
