Issue/Introduction

  • VMware vSphere Lifecycle Manager (vLCM). When attempting to update the ESXi image from the cluster view "Updates" tab, the UI returns the following error: Invalid draft, failed to fetch the draft image.
  • This issue typically presents immediately following an update to the vLCM authenticated download tokens or repository URLs.
  • Log entries in var/log/vmware/vmware-updatemgr/vum-server/vmware-vum-server.log in vCenter looks like below.

Environment

  • VMware vCenter Server 7.0.#
  • VMware vCenter Server 8.0.#
  • VCF9.#

Cause

The image draft failure is caused by incomplete metadata synchronization after updating the vSphere Lifecycle Manager (vLCM) repository URLs and authenticated download tokens.

Resolution

  1. Log in to the vSphere Client.
  2. From the main menu, navigate to Lifecycle Manager.
  3. Select ACTIONS -> Updates -> Sync Updates.
  4. Monitor the Recent Tasks pane and wait for the "Download patch metadata" task to complete successfully.
  5. Navigate back to the target Cluster -> Updates tab.
  6. Select the desired ESXi host image and save the draft settings.
