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

I am on Ubuntu 18.04 and got the same error, was worried for weeks too. Finally realized that gpg2 is not pointing towards anything. So simply run

git config --global gpg.program gpg

And tada, it works like charm.
