after receiving the signed certificate from CA and trying to import it on the key I have the errors:
Using gpg (v2.2.5)
gpg/card> writecertificate 3 < cert_crt.der
gpg: error writing certificate to card: General error
Using pkcs15-init (opensc 0.17.0-3):
pkcs15-init --store-certificate cert_crt.pem --id 3
Using reader with a card: Nitrokey Nitrokey Start (FSIJ-1.2.6-67141547) 00 00
Security officer PIN [Admin PIN] required.
Please enter Security officer PIN [Admin PIN]:
Failed to store certificate: Transmit failed
Keys are 2048RSA generated on the stick. Any suggestion? All other gpg activity work perfect.
The target here is to use the key for the openvpn client.
