 <p>The error is in your configuration. This line:</p> <pre><code>[remote "heroku"] url = git@heroku.com:yourhttp://still-lake-3136.herokuapp.com/.git </code></pre> <p>Is complete nonsense. I don't know how that line ended up there. You must have copy-pasted something from somewhere the wrong way. My guess is it should look like this:</p> <pre><code>[remote "heroku"] url = git@heroku.com:still-lake-3136.git </code></pre> <p>If that does not work you should really follow the instruction here to initiate a remote repository:</p> <p><a href="https://devcenter.heroku.com/articles/git" rel="nofollow">https://devcenter.heroku.com/articles/git</a></p> <p>In that case you can delete the whole <code>[remote "heroku"]</code> section (actually the 5 last lines) from your <code>config</code> file before proceeding with those instructions.</p> <p>One of those two (editing the line, or reinitializing the repository) should fix your problem.</p>
