fprintd failed to activate service 'net.reactivated.Fprint'

[Bill (franksmcb)]

Updated Ubuntu MATE 20.04 on 20200315

Upon boot the option to use fingerprint login was not present. Long delay in being able to input password.

When trying to run sudo the option to use fingerprint is not shown, there is a long delay before it is possible to entry password.

When running any of the fprint commands; fprint-enroll fprint-list, etc... there is a long delay and the following error is show:

"Failed to activate service 'net.reactivated.Fprint': timed out (service_start_timeout=25000ms)"

To remove the long delay it was necessary to uncheck fingerprint authentication in pam-auth-update

I can replicate this is Ubuntu 20.04 as well.

Prior to this series of updates, everything worked correctly.

Thank you for your bug report. Could you attach a 'journalctl -b 0' log from a session where you hit the issue?

What's the output of
$ systemctl status fprintd

Thank you for your bug report, it looks like it needs a rebuild with the new libgusb

 /usr/libexec/fprintd: symbol lookup error: /usr/lib/x86_64-linux-gnu/libfprint-2.so.2: undefined symbol: g_usb_device_get_release, version LIBGUSB_0.1.0

which is a recent regression, fix is on his way, thanks for the report!

Hi,
just wanted to say I got the same error with fprintd:amd64 1.90.1-1ubuntu1 on Ubuntu 20.04. I had to wait 25 seconds before being able to login each time I lock my screen.

auth.log:

Forgot to say that uninstalling the fprint package solved the 25 second response time before login... I don't use the fingerprint reader
