Can't push repository to bitbucket

Hello,

When I try to push my repo given the site's instructions,

cd /path/to/my/repo
git remote add origin git@bitbucket.org:triant/hello_app.git
git push -u origin --all # pushes up the repo and its refs for the first time

it gives me this message:

triant@rails-tutorial:~/workspace/hello_app (master) $ git push -u origin all
conq: repository does not exist.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I don't know what it could be
