1.4.x fails to check the spamassassin tarball signature file
Closed, ResolvedPublic

Description

Release: 1.4.0

Environment

GNU/Linux, glibc-2.3.4, kernel 2.6.11

Description

gnupg-1.4.0 fails to check the spamassassin 3.0.2 tarball detached signature. 1.2.4 checks it without problems. Below is an email exchange with the spamassassin authors.
For example, check these:
http://apache.usp.br/spamassassin/source/Mail-SpamAssassin-3.0.2.tar.bz2
http://www.apache.org/dist/spamassassin//Mail-SpamAssassin-3.0.2.tar.bz2.asc

it might be worthwhile checking that version of gpg. ISTR hearing
from someone recently that their sig verification failed until
they upgraded gpg. Here's the results with 1.2.5:

: jm 61...; gpg --verify ~/DL/Mail-SpamAssassin-3.0.2.tar.bz2.asc
gpg: Signature made Wed Dec 15 19:57:48 2004 PST using DSA key ID 265FA05B
gpg: Good signature from "SpamAssassin Signing Key <release@spamassassin.org>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
Primary key fingerprint: 26C9 00A4 6DD4 0CD5 AD24 F6D7 DEE0 1987 265F A05B

How To Repeat

Just check the detached signature of the spamassassin tarball with gnupg-1.4.0 (perhaps 1.4.x?).

The spamassassin folks are making --textmode signatures.
Since a tarball is not text, this isn't going to work too
well. I've sent them a note about it.
