Package: gpg-agent Version: 2.2.27-2 I can confirm this issue. It still occurs on the newly released stable distribution (bullseye). Linking /usr/lib/gnupg/scdaemon to /usr/bin/false works around the issue, but since I don't know whether that could have unwanted sideeffects, I'd very much prefer a fix in the package or script itself.
Thanks!
