gnus / gpg agent interaction after upgrade to Fedora 23

gnus / gpg agent interaction after upgrade to Fedora 23

[Dave Goldberg]

I've read through the stuff in Bugzilla and a couple other posts.  I get that in Fedora 23 the Gnome password manager no longer manages gpg keys and that gpg-agent is now running separately.  That's OK for working with gpg2 on the command line, but I can't figure out how to get it to work with Gnus (latest git) and Emacs 24.5.1 as distributed with Fedora 23.  I've installed the pinentry-gnome3 and pinentry-emacs packages but whenever Gnus needs to go to, say, .authinfo.gpg, I'm prompted for my passphrase in the minibuffer which works, except that the key is subsequently closed and any subsequent need to get into that file results in another prompt.  What am I missing?

Thanks,

Try (setq epg-gpg-program "gpg2").  By default, I think it uses gpg, which
is not compatible with the gpg-agent that comes with gpg2.

That fixed it for me, at least.

That solves it.  Thanks!

Should the default here be changed?  I'm not very familiar with the epg
stuff...

That is, if pgp2 exists on the system, should that be the default value?

I think yes. Currently (as in Emacs branch emacs-25) it's this:

    (defcustom epg-gpg-program (cond ((executable-find "gpg") "gpg")
                                     ((executable-find "gpg2") "gpg2")
                                     (t "gpg"))
      "The `gpg' executable."
      :group 'epg
      :type 'string)

I suggest this:

    (defcustom epg-gpg-program (cond ((executable-find "gpg2") "gpg2")
                                     (t "gpg"))
      "The `gpg' executable."
      :group 'epg
      :type 'string)

Yup, I agree.

Ok; I've now changed the default in emacs-25.
