Yubikey setup for GPG

Yubikey setup for GPG

[LaFreniere, Joseph]

Does anyone have a working guide for setting up a Yubikey for use 
with GnuPG in Guix System?  It seems that the packaged gpg is 
built with pcsc-lite rather than scdaemon, so much of the 
information in e.g. the Arch wiki is not applicable.

The specific error I'm getting when running `gpg2 --card-status` 
is

> gpg: selecting card failed: No such device
> gpg: OpenPGP card not available: No such device

Hello Joseph,

I'm using a Yubikey with GnuPG on Guix, but don't remember the 
exact
steps I had to do to make it work.

I do have the pcscd-service started with following entry:

(service pcscd-service-type)

I didn't find any other special configuration anywhere else.

Hope that helps,

I had a similar problem with my Librem key. I fixed it by including 
(service pcscd-service-type) in my system configuration, reconfiguring 
my guix system, and making sure I have one of the pinentry packages 
installed and configured.

Thanks for the tip!  I'm reconfiguring right now.  If I don't 
respond in this thread again, any future readers should assume the 
default configuration was sufficient for a YubiKey 5 NFC.
