I don't have access to that platform, but there are two easy things you
can do to help us locate the problem:

1) open any .gpg file directly. Does that fail with the same message?

2) set auth-sources to ~/.authinfo and put some lines in that file. Does
that work?

If (1) fails and (2) works, the problem is in EPA/EPG or its
configuration, and not auth-source. You can use (2) as a workaround
until this issue is resolved.

Thanks

Subject: emacs25.1 + gnus,
 opening message gives: epg-error "no usable configuration" CMS
Date: Tue, 18 Oct 2016 15:59:05 +0200

Ted asked me to follow up here, so reposting and edited version of my
question on gnu.emacs.help.


I just started using Debian Emacs 25.1 + Gnus to get to my email. There
is one message that gives an epg-error that I've not seen before, and
eh, it seems neither has Google (except for pointing me to the source
code)..

Following the error, the message is displayed as raw. The message is
displayed normally under Gnus in emacs24: there the message warns:
[[S/MIME Signed Part:Failed]]

The error suggests that I need to change/add settings to my Emacs init.el or
.gnus file? But what?

It Looks like a misconfiguration or bug for handling Apple Mail s/mime
multipart messages

From my .gnus, s/mime relate settings:

       mm-verify-option 'always
       mm-decrypt-option 'always
       gnus-buttonized-mime-types
       '("multipart/alternative"
         "multipart/encrypted"
         "mul2tipart/signed")


Here is the Backtrace.

Hi,

I've found rather strange solution/workaround.
I've used gpg version 2.0.xx, which worked for me for 25.0.50 I believe.
But for 25.1 I had to upgrade gpg to 2.1.15. Now everything seems to work.

Hi Gijs, can you try Alexey's workaround? Also note my two suggestions
at the bottom, if the workaround doesn't do it.

Alexey reported this for Mac OS but it seems like it may affect multiple
platforms, since you said that you were on Debian.

Thanks
Ted

I'm already on (Debian's) GPGv 2.1.15-4, and I can open .gpg files fine,
such as authinfo.gpg. I can also decrypt gpg buffers
(epa-decrypt-region) fine.

So far, I only get this error "epg-error "no usable configuration" CMS"
when opening an email message by somebody using an Apple to send me an
S/MIME message. In Emacs24, using Gnus, this gives the normal message
headers followed by

[[S/MIME Signed Part:Failed]]
1.  ( ) text/plain          (*) text/html  

in Emacs25, the same message is displayed as raw.

Perhaps it is not at all related to the OP's issue.

I see, thank you for clarifying. The error message was the same so I
hoped it was related. I'll wait for the EPA/EPG maintainer, Daiki Ueno,
to comment since I don't know the internals well enough to be more
helpful.

Thanks
Ted

What is this evaluated to?

  M-: (epg-find-configuration 'CMS)

On my environment, it's is:

Well, that explains something :-) I did not before have this gpgsm
installed. Now I have, but oddly, now gnus takes forever to open the
message.

S/MIME signature verification with gpgsm could take some time.  If it
takes really too long, a usual suggestion is to gather debug output with
(setq epg-debug t).

So I installed gpgsm (Debian Sid's 2.1.15-4).

Without configuring anything gpgsm-related, this gives two kinds of
results:

I have a bunch of email messages, all from the same sender, that come
with s/mime. For these emails, Gnus now takes forever, or /sometimes/ it
pops up a question:

Do you ultimately trust
"CN=AddTrust External CA Root
 OU=AddTrust External TTP Network
 O=AddTrust AB
 C=SE"
to correctly certify user certificates?
[cancel][yes]


If I hit yes, there is a second question, which I have not captured
yet. If I hit cancel - either at the second question, or on the first -
Emacs + Gnus seem to continue to wait forever. When I C-g, the message
is displayed as raw.

I don't yet know why this question, or these questions, is or are
displayed just sometimes, not everytime.

I notice that when trying to open one of these s/mime messages, gpgsm is
trying to verify things: 

/usr/bin/gpgsm --no-tty --status-fd 1 --yes --output /tmp/epg-output314864Xn --verify -- /tmp/epg-signature31486Fit -

/tmp/epg-signature31486Fit looks like the AddTrust certificate,
/tmp/epg-output314864Xn is empty

it takes many minutes.. and I give up waiting, so press C-g

But now, oddly enough, when I open an earlier s/mime message, it is
displayed immediately, and it now shows: 

[[S/MIME Signed Part:Failed]]

which is the behaviour in Emacs24 (without gpgsm).

I have more hit points that you can possible imagine.

Perhaps it needs to download the CRL, which can take a long time.  Watch
the directory ~/.gnupg/dirmngr-cache.d while it hangs.

Thanks!

On Debian, that dir seems to be called ~/.gnupg/crls.d/

Tried opening one of these messages again: and yesterday gave it more
than 30 minutes before I gave up.  ~/.gnupg/crls.d/ now contains a file
(very-long-number.db).

I go to the next s/mime message, and get that question about ultimate
trust again. I say no, and Gnus displays the message with a (valid)
signature, that is unverified (by me). I did not catch the exact output,
sorry.

This happens only once. The next message, from the same sender, this
waiting (verifying) starts again. Even though now there is a file in
~/.gnupg/crls.d/ ?

Is there a way in which I can disable this checking altogether?
Additionally: if no gpgsm is available on the host, perhaps the result
should or could be made similar to what it does in Emacs24, simply
display the message without verification?

I'm still trying to figure out what I'm missing re the Gpgs (bug#24718).

First: if I don't have gpgsm installed, it should just fail, and let
Gnus display the message normally, right?

Second: this might give you an idea:

I notice that for the s/mime messages that seem to cause Gnus & Emacs to
wait forever (over 1 hour yesterday) ps aux shows:

/usr/bin/gpgsm --no-tty --status-fd 1 --yes --output
/tmp/epg-output25808sln --verify -- /tmp/epg-signature258085vt -

If I kill that process, Gnus immediately displays the message normally,
printing:

,----
| [[S/MIME Signed Part:]]
| 1.  ( ) text/plain          (*) text/html      
`----

This is (I think) the same as under Emacs24.


If, while waiting for Emacs Gnus to do its s/mime magic, I can repeat
the gpgsm command I find with ps aux, without the trailing - like so:

,----
| /usr/bin/gpgsm --no-tty --status-fd 1 --yes --output
| /tmp/epg-output25808sln --verify -- /tmp/epg-signature258085vt 
`----

the output is

gpgsm: detached signature w/o data - assuming certs-only
[GNUPG:] NEWSIG
gpgsm: Signature made 2016-10-18 08:56:29 using certificate ID 0x7E75F4FD
gpgsm: invalid signature: message digest attribute does not match computed one
[GNUPG:] BADSIG AC9F7F57E4DF8B867676D82AG4FDACF67E5644FQ /EMail=charles <at> hisdomain

if I repeat it *with* the trailing -

gpgsm: option --output ignored for a detached signature

it waits for something.. until I ^c it

Does this make some kind of sense?

My issue is/was caused by Debian bug #840680. I've just upgraded to
Debian's 2.1.15-6 of dirmgnr and now the time-outs are gone, and the
s/mime certificates get installed instantly in ~/.gnupg/crls.d
