WinRM cannot process the request. The following error occurred while using Kerberos authentication: The computer xxxxx is unknown to Kerberos. Verify that the computer exists on the network, that the name provided is spelled correctly, and that the Kerberos configuration for accessing the computer is correct. The most common Kerberos configuration issue is that an SPN with the format HTTP/xxxxx is not configured for the target. If Kerberos is not required, specify the Negotiate authentication mechanism and resubmit the operation.

The error message clearly shows that SCOM is trying to authenticate using kerberos instead of basic auth, and that it's failing because the linux server isn't registered in Active Directory (at least not under the va700700.ds.dev.accenture.com name).
So you should first check whether that server is joined to AD or not, and if it's supposed to use kerberos authentication or not.

Thanks @CyrAz . I deleted the registry key for Kerberos authentication and was able to install and onboard the server in SCOM. Many Thanks
