Aleksandr Dovydenkov ec2a995c36 tests/fprintd: fix tests to use new GLib version
Tests, that uses GLib.GError with bytes instead of strings type for
message were broken when implementation was changed in GLib update.
Should use GError calls with decode call to fix it.

fprintd
=======

https://fprint.freedesktop.org/

Daemon to offer libfprint functionality over D-Bus
Might eat your kangaroo.

Written in C.

Licensed under the GPL version 2 or any later version (see COPYING).

A PAM login module is included in the 'pam' directory.

Translating
===========

fprintd and pam_fprintd are translated using weblate. Please visit
https://translate.fedoraproject.org/projects/fprintd/ to contribute
translations.

API use cases
=============

- User wants to use the fingerprint reader, and enroll
  his fingerprints, or remove some fingerprints from the database

- Administrator wants to enroll fingerprints for a particular user,
  or remove fingerprints for a particular user

- Laptop/desktop authentication:
  * Check for fingerprint devices
  * Check whether a particular user has any fingerprints enrolled
  * Verify a fingerprint for a particular user, or, if the device
  supports it, verify that the fingerprint matches against
  any of the fingerprints enrolled

- Point Of Sale authentication (in a bar, the fingerprint reader is
  used to see who accesses a particular point of sale/till, in place
  of PIN code authentication and/or tokens)
  * Given a list of users, verify which one has scanned their finger

Debugging
=========

To enable debug output run `systemctl edit fprintd.service` then enter:
```
[Service]
Environment=G_MESSAGES_DEBUG=all
```
Save the result and restart fprintd using `systemctl restart fprintd.service`.

After that, you can grab the logs using `journalctl -u fprintd.service`.
