Overview

Make a git checkout for the public git repo via go-git via ssh-transport does not work because the public key is not added to the github repository.

case 1: Auth via ssh.PublicKeysCallback (SSHAgentAuth)

ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

case 2: AuthMethod is nil. It is error is expected - not found known_hosts (e.g. ssh-keyscan -t rsa github.com >> /root/.ssh/known_hosts) or add ssh.InsecureIgnoreHostKey() in auth method.

unable to find any valid known_hosts file, set SSH_KNOWN_HOSTS env variable

case 3: Auth via ssh.Password

ssh: handshake failed: ssh: unable to authenticate, attempted methods [none], no supported methods remain

case 4: Auth via ssh.PublicKeys

ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

For public repo git checkout from anywhere only via https-transport

case 5: via https

$ ssh-add -D
