Changing git master after cloning
If you’ve cloned a GitHub repository from the original one and not from your forked version and you would like to
change it, you can just edit the
.git/config file in your project and change the URL of the origin remote:
[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = VALUE_WHICH_SHOULD_BE_ADJUSTED
Simple, easy, and most importantly – it works.
