system prompt above error when git push, and then refer to git - GitHub: invalid username or password - Stack Overflow, try to git remote set-url origin git@github.com:englianhu/Coursera-Machine-Learning-for-Trading.git but terminal shows below error:

/cloud/project$ git push

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

fatal: Could not read from remote repository.

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

by refer to Continuing the discussion from Permission Denied Creating SSH RSA Key:, try to create own rsa_key, anyone know how to tune it? Help! Repo not letting me push to Github. - #2 by FJCC is another similar problem but doesn't help
