If you find yourself in the same position as I did where trying to push via an
IntelliJ based IDE isn’t working (in my case PyCharm), and you’re getting the
error: Push failed: fatal: Could not read from remote repository. You might
find that changing your SSH executable from the built-in to the system
native will fix your woes. Pop into the preferences of your project and
navigate to Version Control/Git/SSH executable and flip that setting to
native.
