Cloud Pak tries to install already installed IBM WebSphere Portal server fix pack

An issue is reported with installing middleware fix packs. When you install middleware fix packs, IBM Cloud Pak System installs an already installed IBM® WebSphere® Portal server fix pack.

Apply this workaround when you install the middleware fix packs and if Cloud Pak System attempts to install an already installed the IBM WebSphere Portal server fix pack.

The maintenance logs might have an error message similar to this one:
Invalid CF Selected. The instance is at the selected level or higher. 
Pattern does not support downgrade. Selected fixpack is: CF15 for v8.5 and v9.0. 
Currently running version is: CF15 for v8.5 and v9.0.

Before you apply the middleware fix pack, update the /0config/installedFixPacks file on the failed virtual machine where IBM WebSphere Portal server is installed. Ensure to handle any leading or trailing spaces, or unwanted characters when you edit the file.

To update the file, complete these steps:
  1. SSH to the virtual machine.
  2. Check the contents of the file as follows. 
    cat /0config/installedFixPacks
    The sample result is as follows.
    {"IBM WebSphere Application Server Network Deployment": "8.5.5.8", 
"IBM WebSphere Portal Server": "8.5.0.0 CF05"}
  3. Back up the file.
    cp /0config/installedFixPacks /0config/installedFixPacks.backup
  4. Update the file by using a vi text editor.
    vi /0config/installedFixPacks
  5. Replace the IBM WebSphere Portal server version with the version for which you get the error. The version string can be found in the error message on the management console (maintenance page) for the previous failed attempt.
    The sample update is as follows.
    {"IBM WebSphere Application Server Network Deployment": "8.5.5.8", 
"IBM WebSphere Portal Server": "CF15 for v8.5 and v9.0"}
  6. Save and exit.
