(venv)han@heel:~/desktop/projects/ossko$ heroku keys:add found existing public key: /home/han/.ssh/id_rsa.pub uploading ssh public key /home/han/.ssh/id_rsa.pub... done (venv)han@heel:~/desktop/projects/ossko$ git push heroku master ssh: connect host heroku.com port 22: connection timed out fatal: not read remote repository.  please make sure have correct access rights , repository exists. 

i have follow every steps heroku site.

please me fix error

i have ubuntu 13.4 64bit os

update: here result of git remote -v:

$git remote -v
heroku git@heroku.com:infinite-mesa-xxx.git (fetch)
heroku git@heroku.com:infinite-mesa-xxx.git (push)

try running git remote -v. give more 1 remote, this?

your_app_name git@heroku.com:your_app_name.git (fetch)
your_app_name git@heroku.com:your_app_name.git (push)

if remote depot named other 'heroku' need specify push site instead. example, if remote named ossko, try like

git push ossko master

often have different names remote depots if have more 1 heroku app - can use different name each app.
