[SOLVED] gpg: signing failed: Bad secret key

[Leo Coogan]

I solved my issue so I'm posting this for the benefit of users who might 
have the same issue.

I solved my issue my generating a new key pair because there seemed to 
be no way to work around the incompatibility that caused the key to not 
be able to sign on my NixOS machine. I'm not sure what caused this, but 
it's solved now.
