Unable to install OMSA

If a device displays an Unable to install OMSAUnable to install OMSA status:

  • Verify if the device is reachable from the server where SupportAssist Enterprise is installed.
  • Verify if the device credentials (user name and password) you provided are correct.
  • If the device is running a Windows operating system:
    • Verify if the credentials you provided have administrator rights on the device.
    • Restart the Windows Management Instrumentation (WMI) service on both the server where SupportAssist Enterprise is installed and the remote device.
    • Delete any files available in the C:\Windows\temp folder on the server where SupportAssist Enterprise is installed.
  • If the device is running a Linux operating system:
    • Verify if the Secure Shell (SSH) service is running on the device.
    • Verify if SSH password authentication is enabled (enabled by default).
    • Verify if the credentials you provided have root, super user, or sudo user rights on the device. If you provide the user name and password of a sudo user, ensure that the sudo user is configured for SupportAssist Enterprise. See Configuring sudo access for SupportAssist Enterprise (Linux).
    • Ensure that the device has all the required OMSA dependencies installed. For more information about OMSA dependencies, see the “Remote Enablement Requirements” section in the Dell OpenManage Server Administrator Installation Guide at https://www.DellTechCenter.com/OMSA.
  • Retry the installation of OMSA. See Installing or upgrading OMSA by using SupportAssist Enterprise.
  • If the installation of OMSA cannot be completed successfully even after repeated attempts, log in to the device and manually download and install the recommended version of OMSA on the device. For information on the recommended version of OMSA, see the SupportAssist Enterprise Version 2.0.50 Support Matrix at https://www.dell.com/serviceabilitytools.
NOTE: Upgrade from a 32-bit version of OMSA to a 64-bit version of OMSA is not supported. In this scenario, you must uninstall the existing version of OMSA, and install OMSA by using SupportAssist Enterprise. For instructions to install OMSA by using SupportAssist Enterprise, see Installing or upgrading OMSA by using SupportAssist Enterprise.
