Ubuntu is an open-source Linux distribution based on Debian. It utilizes the APT package management system and is maintained by Canonical Ltd. The project follows a strict release cycle, providing a new version every six months and a Long Term Support (LTS) version every two years.
The operating system runs on the Linux kernel and features the GNOME desktop environment by default. It organizes software into four main repositories: main, restricted, universe, and multiverse. Ubuntu also integrates the snapd daemon for managing containerized software packages known as snaps.
Use Cases
It is widely used for web servers, cloud computing, and developer workstations. Its predictable lifecycle makes it a primary choice for CI/CD pipelines and base images in Docker containers.
According to W3Techs, Ubuntu powers over 30% of all Linux-based web servers. A standard system update procedure involves running sudo apt update && sudo apt upgrade via the command line interface.
