Package: fprintd Version: 1.90.5-2 Severity: grave X-Debbugs-Cc: Asher Gordon <asd...@posteo.net>
Dear Maintainer,
After upgrading fprintd (and libpam-fprintd) from 1.90.1-2 to 1.90.5-2,
it stopped working entirely. Instead of fingerprint authentication,
password authentication is used for login and sudo. I have checked that
/etc/pam.d/common-auth has the right settings.
The problem appears to be that fprintd itself has stopped working, not
the PAM module (which is why I reported this bug in fprintd rather than
libpam-fprintd). When I use any of the fprintd-* commands, it fails as
follows:
$ fprintd-delete asher
Impossible to get devices:
GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1

destination=":1.185" (uid=0 pid=15143 comm="/usr/libexec/fprintd ")
$ fprintd-enroll asher

$ fprintd-list asher
Impossible to get devices:

member="GetDevices" error name="(unset)" requested_reply="0"
destination=":1.185" (uid=0 pid=15143 comm="/usr/libexec/fprintd ")
$ fprintd-verify
Impossible to verify: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied:

From the org.freedesktop.DBus.Error.AccessDenied error, it seems that it
might be a permissions problem. However, the commands do not work, even
when run as root:
$ sudo fprintd-list asher
[sudo] password for asher:
Impossible to get devices:
GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1
matched rules; type="method_call", sender=":1.199" (uid=0 pid=15422
comm="fprintd-list asher ") interface="net.reactivated.Fprint.Manager"
member="GetDevices" error name="(unset)" requested_reply="0"
destination=":1.200" (uid=0 pid=15425 comm="/usr/libexec/fprintd ")
All the above commands returned with an exit status of 1.
Also, if I run /usr/libexec/fprintd manually, I get the following
warning (although a 0 exit status):
$ /usr/libexec/fprintd
(fprintd:15733): fprintd-WARNING **: 13:01:49.856: Failed to get name:
net.reactivated.Fprint
Perhaps this is because fprintd is already running. However
'ps -fe | grep [f]printd' lists no processes.
Thanks,
Asher
