Git/GitHub can't push to master

Question

I am new to Git/GitHub and ran into an issue. I created a test project and added it to the local repository. Now I am trying to add files/project to the remote repository.

Answer 1

Use Mark Longair's answer, but make sure to use the HTTPS link to the repository:

git remote set-url origin https://github.com/my_user_name/my_repo.git

You can use then git push origin master.
