gpg: signing failed: Bad secret key

[Leo Coogan]

This is Nixos.

I don't believe I have two binaries of gpg.

My Nixos config contains:

```nix

         programs.gnupg.agent = {
                 enable = true;
                 enableSSHSupport = true;
         };
```

and the package pinentry-gnome is installed.

I did `which` gpg and gpg2, and gpg2 was a symlink to gpg. So I don't 
believe I have another binary of gpg.


```
