IWS 10.2.x less 10.2.7 installation failure with Liberty 26.0.0.3: A mandatory parameter is request to install the product

Troubleshooting


Problem

The issue is due to a security hardening change in WebSphere Liberty, which no longer allows the use of a hard-coded default key for encryption. 

The change has been introduced in WebSphere Liberty 26.0.0.3 (and related interim fixes for older versions like PH69658).


 

Symptom
