Bug#1021045: gdm3: gdm-fingerprint fails if fprintd is installed but libpam-fprint is not

[Ross Vandegrift]

Package: gdm3
Version: 43.0-1
Severity: normal
X-Debbugs-Cc: rvandegrift at debian.org

Hello,

If fprintd and gdm3 are installed, but libpam-fprintd is not installed, then
users with enrolled fingerprints cannot login.  As soon as I selected my user,
the password box flashes up and away.  Then I'm returned to the original user
list.  gdm-fingerprint logs:

Sep 30 21:22:54 stgulik gdm-fingerprint][2109]: PAM unable to dlopen(pam_fprintd.so): /lib/security/pam_fprintd.so: cannot open shared object file: No such file or directory
Sep 30 21:22:54 stgulik gdm-fingerprint][2109]: PAM adding faulty module: pam_fprintd.so
Sep 30 21:22:54 stgulik gdm-fingerprint][2109]: gkr-pam: no password is available for user

Installing libpam-fprintd fixes the issue.  Perhaps it should be in Recommends
instead of Suggests?

Thanks,
Ross
