bug#19409: 25.0.50; package-list-packages: Failed to verify signature

[Sam Steingold]

I get this:

Debugger entered--Lisp error: (error "Failed to verify signature 
archive-contents.sig")
  signal(error ("Failed to verify signature archive-contents.sig"))
  error("Failed to verify signature %s" "archive-contents.sig")
  package--check-signature("http://elpa.gnu.org/packages/"; "archive-contents")
  package--download-one-archive(("gnu" . "http://elpa.gnu.org/packages/";)

  funcall-interactively(execute-extended-command nil "package-list-packages" 
nil)

  command-execute(execute-extended-command)

Buffer *Error*:

Failed to verify signature archive-contents.sig:
Bad signature from 474F05837FBDEF9B GNU ELPA Signing Agent 
<elpasign@elpa.gnu.org>
Command output:
gpg: onepass_sig with unknown version 255
gpg: Signature made Thu Dec 18 05:05:02 2014 EST using DSA key ID 7FBDEF9B
gpg: BAD signature from "GNU ELPA Signing Agent <elpasign@elpa.gnu.org>" 
[unknown]

I have
$ gpg2 --version
gpg (GnuPG) 2.0.26
libgcrypt 1.6.2

what do I do now?
