I used Yosemite. Upgraded to El Capitan, later updated GPG.
Now when I'm trying to sign commit, it fails:

$ git commit -S -m 'update' error: gpg failed to sign the data
fatal: failed to write commit object

Also when I run gpg:

$ gpg gpg: Go ahead and type your message ...
Test gpg

gpg: no valid OpenPGP data found.
gpg: processing message failed: Unknown system error

Expected
It should sign commits

   Did you end up figuring this out? Also having this same issue.

   No. Still broken, I spent couple hours trying to figure this out, but I'm so technically savvy about encryption utilities.
   I believe it is something withing GPG itself. I have plan to completely remove all gpg stuff and install it from scratch, but I don't want to because I'm afraid to lost keys etc.
   Also, Apple Mail signs emails so I'm sure it is something withing their command line utility. They have something interesting about sockets/pipes when encryption is happening. I suspect, they changed format or something like that.

   Hi Phil,

   there seem to be conflicting version of gnupg installed on your system.
   From your debug info we see that you have at least gpg-agent installed in /opt/local/bin/gpg-agent
   As far as I remember macports used /opt/local for their tools, so you might want to uninstall gnupg from macports and only use ours.
   In addition it appears that there's something wrong with your gpg-agent.conf file
   Could you post that so we can have a look?

   Thanks.

   Hi Luke,

   I uninstalled gpg-agent, now Apple Mail cannot sign emails.

   $ gpg gpg: Go ahead and type your message ...
   fnngd
   fdmzgfd

   gpg: no valid OpenPGP data found.
   gpg: processing message failed: Unknown system error

   Looks like everything is broken.

   Hi Phil,

   from the debug info it looks like the macports version of gnupg is heavily interfering with our version. It would be great if you could remove either the macpports version or our version and see if the problem still persists.

   The macports version also sets an environment variable for gpg-agent which is not at all what that environment variable should look like. Not sure why they're doing it, but it also prevents gpg-agent from functioning properly. We've seen a similar case with macports before.
