4.4 Server Configuration

All configuration settings were defined in advance as part of the planned communication platform. This included network configuration as well as the installation of additional repositories and program libraries. By replacing hardware components and applying program and distribution updates, dependency trees of software libraries may change and no longer function correctly. Therefore, during system upgrades—in this case Ubuntu 16, 18, 20, and 22, as well as the transition from Python 2 to Python 3—it becomes necessary to search for new approaches in order to meet the required specifications. For this purpose, suitable solution strategies are evaluated on a virtualized operating system prior to deployment.
