I'm using Tails (2.9.1) and so far I never had a problem to send someone an encrypted message with GnuPG. But for some reason someone can't read my messages. The Public Key Block of this guy says that he uses APG v1.1.1. I can import his public key to my keyring and encrypt the message but for some reason he can't read it. Did anyone else had this Problem and know how to solve it? I really need to get in contact with him...
Problem is on his end. APG hasn't been updated in 2 years
