You have to do some work to set things up before you can push anything
to github.
1. change your URL as Jens directed. I just removed my "origin" and
added github as my new "origin"
origin ssh://g...@github.com/apache/geode.git
2. open gitbox.apache.org in your browser. In the middle of the screen
is an icon you must click & link your Apache and Github accounts,
logging into each with oauth.
3. If you haven't done so already you also need to put your Github ID in
your Apache profile settings (down toward the bottom of the settings
page), There's a link to this settings page on the account-linking
page. If you haven't set up 2 phase authentication on Github you can
also do that through the account-linking page.
4. wait for half an hour for things to sync up. You'll know it's done
when you're able to push to the Github repo.
