Hi
I had exactly the same issue with this error message in log file (C:\Users\Administrator\AppData\Local\Temp\2\vcsaUiInstaller ):
- debug: initiateFileTransferFromGuest error: ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.
- debug: Failed to get fileTransferInfo:ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.
- debug: Failed to get url of file in guest vm:ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.
- debug: [1]pollRpmInstallProgress:getGuestFileErr:ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.
To solve it, I launched the Management Console from VCSA (F2 Customize system) and reset VCSA appliance root password with the same one given during installation process.
