Kubuntu
What Kubuntu is
Kubuntu is a community-developed Ubuntu flavour that combines Ubuntu with the KDE Plasma desktop and KDE applications. The Kubuntu 26.04 LTS release is available for desktop PCs and laptops with AMD64 (x86-64) processors, and receives security and maintenance updates through April 2029. It includes KDE Gear applications including Dolphin, Konsole, Okular and Kdenlive, alongside Firefox and LibreOffice. Users can browse applications through Discover, with APT package management also built in; applications from the Ubuntu archive and Snap packages are supported. The desktop adds text recognition in Spectacle, an integrated on-screen keyboard and Plasma Wayland as its default supported session. Kubuntu describes Plasma as easy to use by default and customizable. Releases come every six months, while LTS versions arrive every two years in April. For 26.04 LTS, security updates and bug fixes cover KDE Frameworks, Plasma 6.6 LTS and KDE applications throughout the release lifecycle. Kubuntu can be installed on a physical computer or used through live USB installation media. The community points users to Discourse, KDE Forums, Ask Ubuntu, Kubuntu forums and Matrix support rooms. The 26.10 beta is for testing and may be unstable.
