Could not read from remote repository

Got this error when pushing code to GitHub:

Developers-iMac:experiment-react-route-based-lazy-load dev$ git push -u origin master
Warning: Permanently added the RSA host key for IP address '13.250.177.223' to the list of known hosts.
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

One solution that works:

Developers-iMac:experiment-react-route-based-lazy-load dev$ git remote set-url origin https://github.com/ienablemuch/experiment-react-route-based-lazy-load

Make gpg-signing work with WebStorm git commit

Add these two lines, on ~/.gnupg/gpg.conf:

no-tty
use-agent

Install the following tools using brew:

$ brew install gnupg gnupg2 pinentry-mac

Add this in ~/.gnupg/gpg-agent.conf (gpg-agent.conf not yet existing on my machine):

pinentry-program /usr/local/bin/pinentry-mac 

Run this:

$ git config --global gpg.program $(which gpg)
