QuarkOS 26.04 “Resolute” LTS is now available, based on Ubuntu 26.04 “Resolute Raccoon” and shipping KDE Plasma 6.6 as the default desktop environment. The release follows Ubuntu’s 5-year LTS support cycle (supported until at least May 2031, potentially May 2036 if Ubuntu extends to 10 years upstream).
Key highlights
- Default DE: KDE Plasma 6.6
- Base: Ubuntu 26.04 LTS
- Snap-minimised: QuarkOS deliberately avoids snap-based packages in favour of stable APT packages
- ISO size: 2.5 GB
- Trinity Desktop Environment edition (Trinity 14.1.6) is planned but not yet available; the last Trinity ISO remains QuarkOS 24.04
