I have a new problem, I installed kgpg and generated the key, the process went well, when I encrypted a file and then decrypted it, I was prompted with: Error trying to decrypt wallet qpo using GPG. If you are using a smart card, please make sure you have it inserted and try again.
GPG error for improper ioctl operation on device
I checked and someone said to add in ~/.bash_profile.
GPG_TTY=$(tty) export GPG_TTY
But for me, it didn’t work.
