In the v18.0.0 or 18.0.5 NextGen gateway, there is a known issue where users faced difficulties upgrading to v18.1.0 from the OpsRamp UI.
To resolve this issue, follow the below steps:

  1. Log in to the Gateway VM or Kubernetes cluster where the Gateway is running.
  2. Use the following command to edit the vprobe-updater-cm configmap and nextgen-gw-updater-cronjob cronjob:
    kubectl edit configmap vprobe-updater-cm -n <NameSpace>
    
    kubectl edit cronjob nextgen-gw-updater-cronjob -n <NameSpace>
  3. Change the updater images version to 2.2.5.
    Example:
    image: us-docker.pkg.dev/opsramp-registry/gateway-cluster-images/nextgen-updater:2.2.5
  4. Try updating the Gateway again through the OpsRamp Portal.
