Try forcing a restart of the gpg-agent with pkill gpg-agent

➜ gpg --card-status
gpg: selecting card failed: Service is not running
gpg: OpenPGP card not available: Service is not running

➜ pkill gpg-agent

➜ gpg --card-status

  • For me pkill gpg-agent did not work, but gpgconf --kill gpg-agent restarted the agent well and the yubikey start to work as expected.

It seems like pcscd.service is inactive by default, have you tried (re)starting it?

sudo service pcscd restart

    in my case restarting gpg-agent didn't help and pcscd service was running. Only after restarting pcscd service I was able to read the key. I'm on Fedora 38, GPG v2.4.0, pcsc-lite v1.9.9

  • Fedora 39, GPG v2.4.4, pcsc-lite v2.0.1 also requires pcscd restart after each hotplug of YubiKey.
