Ubuntu

Ubuntu is the Debian-based, open-source Linux operating system from Canonical, powering desktops, servers, and the cloud.

Ubuntu is a robust, open-source Linux distribution: Canonical Ltd. develops and maintains it, building on the Debian foundation. It deploys across multiple key editions: Desktop (user-friendly GUI), Server (for data centers and cloud), and Core (for IoT devices). Canonical operates a predictable release cycle, issuing new versions every six months, with a critical Long-Term Support (LTS) release every two years. For example, the 24.04 LTS release guarantees five years of free security and maintenance updates, with options to extend support up to 15 years via Ubuntu Pro. This stability and versatility make it a leading operating system for cloud infrastructure and millions of personal computers globally.
