This article delves into the "repository access denied. access via a deployment key is read-only" error encountered when cloning a repository from Heroku and pushing to BitBucket in a Git workflow. By analyzing Q&A data, it reveals the root cause: misuse of deployment keys instead of account SSH keys. Deployment keys grant read-only access, preventing write operations like git push. The article explains SSH key mechanisms, differences between deployment and account keys, and provides step-by-step solutions, including configuring BitBucket account SSH keys, removing misconfigured deployment keys, and verifying authentication via SSH debugging. It also discusses related concepts like forced commands and permission models, offering a comprehensive understanding of Git remote repository access control.
