Definition

Overview
Ubuntu is built on top of Debian, one of the oldest and most established Linux distributions, but adds its own installer, package repositories, default software selection, and release cadence aimed at making Linux more approachable for both newcomers and enterprises. Canonical ships a new Ubuntu release roughly every six months, with Long Term Support (LTS) versions released periodically and supported with security updates for an extended period, making LTS releases the default choice for production servers. On the desktop, Ubuntu is often recommended as an entry point into Linux due to its polished installer, GNOME-based desktop environment, and large community documentation base. On servers and in the cloud, Ubuntu is one of the most widely available base images across major cloud providers, and is frequently used as the base layer for Docker container images, given its balance of a small footprint and broad package availability. Most day-to-day interaction with Ubuntu servers happens through the command line via Bash or another shell, making comfort with shell scripting and package management (`apt`) a practical prerequisite for anyone administering Ubuntu systems in production, whether on AWS or another cloud. A course like Linux & Shell Scripting covers this foundation directly.
