Hello world :-)

Today my gpg-agent stopped working, probably after recent pkg upgrade, no
configuration change.

Problem is noted on forums too:

https://forums.freebsd.org/threads/smart-card-yubiko-stopped-working.96372/

Seems like caused by PCSCD. Looks like access definitions changed?

# pcscd -f
00000000 ../src/auth.c:148:IsClientAuthorized() Error in authorization:
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: get_kinfo_proc() failed

USB device permissions are fine. Card can be read with yubikey utilities:

% ykinfo -s
serial: [REDACTED]

Another client also fails to read the card for the same reason:

% yubikey-agent -l /[REDACTED]/S.gpg-agent.ssh

Any hints welcome. This is kinda blocker for all token based ssh connections
:-(
