I have found that the problem is the expired X.509 certificates. Here is my easy workaround to solve this bug.
1. Remove the file where the X.509 certificates are stored. rm usr/share/gnupg2/com-certs.pem 2. Remove your gnupg configuration folder. rm home/benutzer/.gnupg/ That's all. Should work for every version. Enjoy. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
