Why Does My CircleCI Go Project Fail with the \'agent key returned incorrect signature type\' Error on Non-Master Branches?

Error: "agent key returned incorrect signature type" When Using GitHub and CircleCI with Go Projects

When utilizing CircleCI with Go projects hosted on GitHub, users may encounter an error message stating, "agent key RSA SHA256: ... returned incorrect signature type." This error, unrelated to the actual codebase, occurs during a git pull operation on a non-master branch.

Issue 1: SSH Agent Incorrect Signature Type

The "agent key returned incorrect signature type" warning signifies that the SSH agent involved provided an invalid signature data. RSA SSH keys allow for multiple hash algorithms, including SHA-1, SHA-256, and SHA-512. By default, RSA keys implied SHA-1 hashing. However, this error indicates that the SSH connection negotiated using a different signature algorithm (SHA-256 or SHA-512), while the SSH agent provided an SHA-1 signature.

This error is not critical, but the remote server may reject the connection due to lack of support for SHA-1 signatures.

Issue 2: Missing Git Remote Configuration

The accompanying Git error message informs the user that a git pull operation was attempted without a remote for the current branch. This occurs when using go get on an existing repository, as it tries to update the existing repository.

Go's go build command is typically sufficient for installing dependencies. If more complex operations are required, Git itself should be used, as go get is not designed for such scenarios.
