I have been trying to decrypt messages with public pgp keys (all of which are imported into my key ring) and I always get an error saying “decryption failed no secret key” this is a problem as the messages are important and I need to be able to see them. I have tried several different public keys and get the same result. If I myself encrypt a message with another person’s public key, and then try to decrypt it and read it I get the same error message. Am I doing something wrong? I’ve used tails years ago and have never had this issue.
