When sending an email to myself, which is signed with my own GPG key, I get the following error:
"Message was signed by MYEMAILHERE (Key ID: 0x79E52FAB08F75808).
The signature is valid, but the key's validity is unknown."
It worked flawlessly on my deceased notebook, but I get this error message on my new desktop installation. What could be the reason?
