Understanding the Error

When attempting to install a package from a private repository using pip, you may encounter the following error message:

ERROR: Command errored out with exit status 128:
command: git clone -q ‘ssh://****@github.com/my_projects/ib_client’ /tmp/pip-req-
build-ivumdv23
cwd: None
Complete output (7 lines):
key_load_public: invalid format
Warning: Permanently added the ECDSA host key for IP address ‘AA.BB.CC.DD’ to the list
of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

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

This error indicates that there is an issue with the SSH configuration and access rights required to clone the private repository. It is essential to understand the root causes behind this error before proceeding with troubleshooting.

Common causes of this error include incorrect SSH configuration, invalid public-private key pair, insufficient access rights, or problems with the repository itself. By identifying the specific cause, you can take appropriate steps to resolve the issue.

Troubleshooting Steps

1. Verifying SSH Configuration: To begin troubleshooting, check your SSH client configuration. Ensure that the SSH client is properly configured and has the necessary information to establish a secure connection. Additionally, review the known hosts file and confirm that the relevant IP address and hostname are correctly added.
2. Validating Public-Private Key Pair: Verify the integrity of your public-private key pair. Ensure that the keys are generated correctly and match each other. You should be able to connect to the SSH server using these keys and successfully clone the private git repository.
3. Configuring SSH Client Correctly: Review the SSH client configuration files, such as ~/.ssh/config or /etc/ssh/ssh_config. Check for any misconfigurations or missing parameters that may be causing the error. Make the necessary modifications to ensure a reliable connection.
4. Resolving Permission Denied Error: The “Permission denied (publickey)” error suggests that your SSH key does not have sufficient access rights to the repository. Confirm that you have the necessary permissions and access granted by the repository owner. If needed, contact the owner to ensure your access rights are correctly configured.

Step-by-Step Guide to Solve the Error

1. Step 1: Update SSH Configuration: Open your SSH client configuration file, usually located at ~/.ssh/config. Add the appropriate host and identity information for the private repository. Specify the SSH key file and ensure that the configuration matches the repository settings.
2. Step 2: Regenerate Public-Private Key Pair: If you suspect issues with your current key pair, generate a new one. Follow the appropriate steps to create a new public-private key pair and replace the existing ones. Remember to securely store the private key and update the public key on the repository server.
3. Step 3: Testing SSH Connection: Test the SSH connection by running ssh [email protected]. Verify that the connection is successful and does not prompt for any password or passphrase. If the connection fails, review the SSH client configuration and ensure the key pair is correctly set up.
4. Step 4: Clone the Private Git Repository: Attempt to clone the private git repository using the git clone command. Verify that the repository is accessible and that the cloning process completes without errors. If any issues persist, double-check your SSH configuration and access rights.

Additional Tips

In addition to the troubleshooting steps outlined above, consider the following tips:

• Review firewall and network settings: Ensure that the necessary ports are open and that there are no network restrictions or firewall rules blocking the SSH connection.
• Seek assistance from the repository owner or support team: If you have followed the troubleshooting steps and still encounter issues, reach out to the repository owner or support team. They may be able to provide further insights or resolve any repository-specific problems.
• Keep SSH client and Git versions up to date: Regularly update your SSH client and Git installations to benefit from the latest bug fixes, security patches, and compatibility improvements.
