Certificate signing operation was not successful - signing and managing Unix/Ubuntu agent

I cannot get the agent reinstalled on some servers, the discovery wizard fails on signing and managing the certificate.

Task invocation failed with error code -2130771918. Error message was: The SCXCertWriteAction module encountered a DoProcess exception. The workflow "Microsoft.Unix.Agent.GetCert.Task" has been unloaded.

Hi @BrianWright-0689,

The agent needs to be installed with the root account or an account that SUDO grants root access to.

  • What version of Ubuntu are you trying to monitor?

  • What is your SCOM version?


Here's an older forum thread with some links that may be helpful to your issue:
