Sup0108 A Deployment Or Update Operation Is Already In Progress Best !exclusive! May 2026

Guide: Troubleshooting “SUP0108: a deployment or update operation is already in progress” (best practices)

6. Integration with Existing Error sup0108

This review focuses on the context of Azure Arc-enabled servers, where this specific Support Topic ID is most commonly generated.

1. Core Components

| Component | Purpose | |-----------|---------| | Deployment Lock Manager | Tracks active deployments (e.g., in Redis, DB, or cloud lock table) | | Request Queue | Holds pending deployment requests | | Polling / Webhook Notifier | Alerts user when lock is released | | Idempotency Key | Optional, to avoid duplicate deployment requests |

1. A Stuck WSUS Server Cleanup

WSUS has a built-in cleanup wizard (or maintenance task). If this task is triggered manually or via a script and does not complete (due to a timeout or DB lock), WSUS will hold an internal flag saying "Busy." ConfigMgr interprets this as a deployment operation. Map error sup0108 to the "lock acquired" check

2. Cancel the Running Operation

If the deployment is stuck or taking too long and you want to start fresh, you can cancel the current rolling update.

For Docker CLI:

docker service update --rollback <service_name>

Note: This attempts to roll back to the previous stable version, which usually clears the lock.

Alternatively, strictly stopping the update isn't always a direct flag, but forcing a rollback is the standard way to "unlock" it. This review focuses on the context of Azure

4. Recent Upgrade of ConfigMgr or WSUS

After upgrading to a new version of Configuration Manager (e.g., 2207 to 2303), the WSUS configuration might be reset, or a background migration task might still be running.

3. Quick diagnostics (ordered)

  1. Check deployment system UI/dashboard for active jobs and timestamps.
  2. Inspect logs of the deployment service and target nodes for start/completion errors.
  3. Query job/lock records:
    • CI/CD: list running pipeline jobs.
    • Orchestrator: list active operations (e.g., kubectl get events, helm history).
    • Device managers: check device status and pending updates.
  4. Look for lock files or semaphore entries on controllers/agents (common paths: /var/lock/, /tmp/, application data dirs).
  5. Check DB table (deployments/operations) for rows with status = in_progress / running / pending and timestamps.
  6. Verify no automated scheduler (cron, GitHub Actions, Jenkins triggers) started a duplicate run.
  7. Confirm network connectivity between controller and targets — a lost connection may leave operations marked active.

Understanding SUP0108 Error

The SUP0108 error indicates that there is an ongoing deployment or update operation. This means that the system is currently busy with another task related to deployment or updating, and it cannot start a new operation until the existing one is completed. kubectl get events
