Ubuntu released version 2020 LTS (Focal Fossa) on April 23, 20.04, for which it will provide support until April 2025. It has even received an update since the release of 20.04, so currently 20.04.1 LTS is the latest version of this Ubuntu line. In this description, we will use version 20.04.1 to create the latest family member for the minimum servers. On this page we make the necessary additional settings and fine-tuning.

In this description, we will build the Ubuntu 18.04 LTS (Bionic Beaver) minimal server, which will be the building block of many more descriptions. Ubuntu has been providing support for members of the LTS (Long Term Support) family for five years, so we will receive updates for version 18.04 until April 2023. This provides an excellent basis for installing a server - which we want to run securely for many years to come. On this page, we will complete the installation by performing some command line settings.
