Good day!To ensure your Azure Arc-enabled RHEL 8.10 VM is properly synchronized with Azure Update Manager, begin by verifying the health of the Azure Connected Machine agent by checking the status of the himdsd and azcmagent services using systemctl,
sudo systemctl status himdsd sudo systemctl status azcmagentand confirm the agent version with the azcmagent show command.
Next, confirm that the VM is correctly reporting to Update Manager by running the az resource show command with the appropriate namespace, resource type, VM name, and resource group.
az resource show --namespace Microsoft.HybridCompute --resource-type machines --name <VM-Name> --resource-group <RG-Name>Additionally, verify that the required extensions — DependencyAgentLinux and AzureMonitorLinuxAgent — are installed using az connectedmachine extension list, as these are essential for inventory collection and patch reporting.
az connectedmachine extension list --machine-name <VM-Name> --resource-group <RG-Name>Look for:
DependencyAgentLinux
AzureMonitorLinuxAgent
Lastly, ensure that Periodic Assessment is enabled in Update Manager via the Azure portal to allow the system to automatically and regularly evaluate the VM for pending updates, keeping the compliance status accurate and up to date.
Please let me know if you face any challenge here, I can help you to resolve this issue further

Before trying to sync the update manager with Azure Arc enabled servers, verify the deployed region of the server is supported according to the MSDoc.
Also, check if there are any third party dependency updates are there as detailed in this MSDoc to avoid the conflict while syncing.
