bitbucket git repository access denied for additional ssh key

Question

I can not push or clone my repositories using ssh. I'm using Ubuntu 16.04. I read this answer and followed the official tutorial but still I cannot access my repository in BitBucket.

1. I create a new repo on BitBucket.

2. I create an additional ssh-key following the tutorial.

3. Then I add all development keys to my account and not for Deployment.

4. I clone the repo using the command:

   git clone ssh://**localuser**@bitbucket.org/**repoUser**/repo.git
   

   and I get this answer:

Cloning into 'countingsystemv5'... repository access denied. deployment key is not associated with the requested repository. fatal: Could not read from remote repository.

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