gpg failed to sign the data fatal: failed to write commit object [Git 2.10.0]

Question

I followed few articles over the pretty attributes on Git 2.10 release note. Going through which upgraded the git to 2.10.0 and made changes to global .gitconfig

Answer 1

Very much like @birchlabs, after a lot of digging/searching I found that it wasn't GPG, but rather GPG Suite. I did cask reinstall gpg-suite and it solved it for me.
