[EDIT 2: this comment was created before I realized that I was working on two different systems and the changes from the previous comment were not applied to both. Recommend ignoring this comment.]
Thank you, the card works better now but only as root. [EDIT - pkcs15-tool still doesn’t recognize the new key though as root or non root. I was wrong about root access working. Sorry. this whole post is a mess. I’m deleting bad information to clean it up]
On my primary system I am using the original key as my non-root user with pkcs15 but the second key is not working. I have fresh .gnupg folders with the public key imported for both root and the non-root user so the process and data should be the same for both and the key imported into both librem keys is the same.
I’m on Kubuntu 19.10 and have added the udev rules as mentioned here (watch out for weird quotes)
also tried setting GNUPGHOME to ~/.gnupg as mentioned somewhere in these posts
