You can install CUE Semantic on any Ubuntu or RedHat / CentOS machine in your network. It does not need to be installed on the same machine as CUE (although it can be). Before you try to install it, make sure that:
You have installed Java 11 or higher on the machine where CUE Semantic is to be installed.
You have credentials for accessing Stibo DX's software repositories.
You have credentials for accessing the Atilika semantic analysis service.
