Error waiting for SSH: Packer experienced an authentication error : using vsphere-iso-CodePudding

getting below error while running packer using vsphere-iso builder.

Error waiting for SSH: Packer experienced an authentication error when trying to connect via SSH. This can happen if your username/password are wrong. You may want to double-check your credentials as part of your debugging process. original error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none password keyboard-interactive], no supported methods remain

config.json

    "communicator": "ssh",
    "ssh_username": "{{user `ssh_username`}}",
    "ssh_password": "{{user `ssh_password`}}",
    "ssh_timeout": "30m",

username and password is coming from Jenkins at run time. same has beed updated in autounattend.xml , if i hard-code the credential in config.json file then its working fine. dont know what's the issue

CodePudding user response：

I got the solution as below

In autounattend.xml file password was given as plain text true , which needs to be change to false.
