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

Mark Longair's solution using git remote set-url... is quite clear. You can also get the same behavior by directly editing this section of the .git/config file:

before:

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git://github.com/my_user_name/my_repo.git

after:

[remote "origin"]
    fetch = +refs/heads/*:refs/remotes/origin/*
    url = git@github.com:my_user_name/my_repo.git

(And conversely, the git remote set-url... invocation produces the above change.)
