I have an expired pgp key of someone I imported years ago.. so I downloaded the updated key from the interested person's website and now the expiration has shifted, good! ... not! Because even after accepting the key and closing-opening Thunderbird, I still see the uncertain signature's warning! How to solve this problem?
This is the key: 3EEA4D83582EDB05A70481B4A38042F607D623DA
this the URL where the downloadable .asc is located: https://www.kraken.com/en-us/features/security/pgp
Thanks in advance!
