Causes of the Git error “Permission Denied (publickey keyboard-interactive)”

There are several reasons why you may encounter the “Permission Denied (publickey keyboard-interactive)” error while using Git. It is essential to understand these causes so that you can identify the root cause of the error and take the necessary steps to fix it. The following are the most common causes of this error:

1. Outdated SSH key: The SSH key is an authentication token that allows Git to verify your identity with the remote repository. If your SSH key is outdated or no longer matches the key registered with the remote repository, you may encounter the “Permission Denied (publickey keyboard-interactive)” error.
2. Incorrect permissions: Another common cause of this error is incorrect permissions on the SSH key. If the permissions are set incorrectly, Git may not be able to read the key, leading to the error.
3. Incorrect username or email: If the Git username or email you are using does not match the username or email associated with the SSH key, Git may not be able to authenticate your identity, leading to the error.
4. Firewall or proxy issues: Finally, if your network is using a firewall or proxy, this can interfere with the communication between Git and the remote repository, leading to the error.

Identifying the root cause of the “Permission Denied (publickey keyboard-interactive)” error is essential for resolving it. Once you have identified the cause, you can take the necessary steps to fix it and continue using Git with confidence.

Solutions to fix the Git error “Permission Denied (publickey keyboard-interactive)”

There are several solutions to fix the “Permission Denied (publickey keyboard-interactive)” error in Git. The appropriate solution depends on the cause of the error. In this section, we will explore the various solutions to this error and how to implement them.

Regenerating SSH keys: If the SSH key is outdated or no longer matches the key registered with the remote repository, you need to regenerate your SSH keys. This process involves creating a new SSH key and updating it with the remote repository. To regenerate SSH keys, you need to follow the below steps:

Open Git Bash or Terminal on your computer.

Type the following command:

ssh-keygen -t rsa -b 4096 -C “your_email@example.com”

Follow the prompts to create a new SSH key.

Add the SSH key to the ssh-agent by typing the following command:

eval “$(ssh-agent -s)”

ssh-add ~/.ssh/id_rsa

Update the new SSH key on the remote repository.

Verifying SSH key permissions: If Git cannot read the SSH key due to incorrect permissions, you need to verify the SSH key permissions and correct them if necessary. To verify and correct the permissions, follow these steps:

Open Git Bash or Terminal on your computer.

Type the following command:

chmod 700 ~/.ssh

chmod 600 ~/.ssh/id_rsa

Verify that the permissions have been updated by typing the following command:

ls -al ~/.ssh

Updating Git username and email: If the Git username or email you are using does not match the username or email associated with the SSH key, you need to update the Git username and email. To update your Git username and email, follow these steps:

Open Git Bash or Terminal on your computer.

Type the following command:

git config –global user.name “Your Name”

git config –global user.email “your_email@example.com”

Checking Firewall and proxy settings: If your network is using a firewall or proxy, you need to check the firewall and proxy settings and correct them if necessary. To check the firewall and proxy settings, follow these steps:

Contact your network administrator to determine the correct firewall and proxy settings for your network.

Update the Git configuration file to use the correct firewall and proxy settings by typing the following command:

git config –global http.proxy http://proxy.example.com:8080

git config –global https.proxy https://proxy.example.com:8080

By following the above solutions, you should be able to resolve the “Permission Denied (publickey keyboard-interactive)” error and continue using Git without any issues.
