Hi, I downloaded and imported the keys from: http://savannah.gnu.org/project/memberlist-gpgkeys.php?group=bison
but it seems that the key used to sign bison-2.4.3.tar.bz2 expired on 19 January 2011: $ gpg --verify bison-2.4.3.tar.bz2.sig bison-2.4.3.tar.bz2 gpg: Signature made Fri 06 Aug 2010 02:49:29 BST using DSA key ID 263DF280 gpg: Good signature from "Joel E. Denny <jde...@clemson.edu>" gpg: Note: This key has expired! Primary key fingerprint: 6F2C 36CB 314C A6A5 0A44 391B C2DC 77AD 263D F280 $ gpg --list-keys 263DF280 pub 1024D/263DF280 2010-01-19 [expired: 2011-01-19] uid Joel E. Denny <jde...@clemson.edu> The signature appears to have been verified successfully, so I'm not sure if this is a problem or not? _______________________________________________ help-bison@gnu.org http://lists.gnu.org/mailman/listinfo/help-bison
