This is for secure signing, when you are doing something like
git commit -S -m "message"
Solution
first make sure you have register your signing key
git config --global user.signingkey YOUR_KEY
where YOUR_KEY can be retrieved by gpg --list-secret-keys --keyid-format=long
then try to reload the agent
echo RELOADAGENT | gpg-connect-agent
then re-commit. If you still get the error then kill the agent and launch it again
gpgconf --kill gpg-agentgpgconf --launch gpg-agent
and may be reload it one more time
echo RELOADAGENT | gpg-connect-agent
