握手失败:ssh:无法验证，尝试的方法[无密码键盘交互]，没有支持的方法仍然存在 [英] handshake failed: ssh: unable to authenticate, attempted methods [none password keyboard-interactive], no supported methods remain

问题描述

这个问题的问题类似于SSH 失败时使用 Packer 构建 RancherOS

但是，我的 Packer 的行为是不同的.我明白了

However, the behavior of my Packer is different. I get

==> virtualbox-iso: Error waiting for SSH: ssh: handshake failed: ssh:
unable to authenticate, attempted methods [none password keyboard-
interactive], no supported methods remain

我不知道为什么 Packer 无法通过 ssh 进入虚拟机.我可以看到 VirtualBox 控制台屏幕位于登录输入上.然后它超时并被打包程序丢弃.

I am not sure why Packer is not able to ssh into the VM. I can see VirtualBox Console Screen sits on a login input. Then it timeouts and gets discarded by packer's process.

}

cloud-config.yml

#cloud-config
rancher:
  ssh_authorized_keys:
    - ssh-rsa AAA ... some VALID RSA [e-mail]
  network:
  interfaces:
    eth0:
      dhcp: true
    dns:
      nameservers:
        -8.8.8.8
        -8.8.4.4

在构建器中添加了这些行，并从供应商中删除了它们的等价物.这仍然没有解决我想要的其他步骤，但至少上传了cloud-config并且可以进行配置.

Added these lines in the builder and removed their equivalents from provisioners. This still does not solve the other steps that I want to have, but at least cloud-config is uploaded and configuration can be done.

      "http_directory":"http",
      "boot_command":[
          "<esc><esc><enter><wait>",
          "wget http://{{ .HTTPIP }}:{{ .HTTPPort }}/cloud-config.yml <enter>",
          "sudo ros install -d /dev/sda -f -c cloud-config.yml -i rancher/os:{{ user `ros_version` }}",

推荐答案

RancherOS 默认没有启用 ssh 密码.请参阅问题 #1467

RancherOS doesn't have ssh password enabled by default. See issue #1467
