Signing with a Yubikey fails until I run `gpg --card-status`
Which of our tools is giving you problems? GPG services (probably)
Attach a screenshot of the version info for all installed components (how to: https://gpgtools.tenderapp.com/kb/faq/where-can-i-find-version-info...):
Describe your problem. Add as much detail as possible. I set up my Yubikey to hold my encryption, signing, authentication subkeys. The public key is stored in GPG Keychain. When I first insert the Yubikey and then try to sign a file from the service menu it fails, until I run gpg --card-status, after which I can sign successfully until I unplug/re-plug the Yubikey.
I think I'm not the only one with this problem (see first answer): https://security.stackexchange.com/questions/196429/gnupg-public-ke...
What did you expect instead I expect the signing to always work without the gpg --card-status hack
Describe steps leading to the problem. Plug in a Yubikey with a signing key, try to sign anything, watch it fail. Run gpg --card-status, try to sign a file again and it will work until the key is unplugged. Rinse and repeat.

Hi Marco,
thank you for taking the time to report this problem. We apologize for the bad experience.
This issue is likely related to a regression introduced in GnuPG 2.2.24 which should be fixed in 2.2.25.
Could you please download and install our latest hotfix GPG Suite and see if that solves your problem.
All the best,
Steve
