Ubuntu Linux 25.10, dubbed "Questing Quokka," has officially launched, showcasing a range of advanced open-source technologies and enhanced accessibility features. This version introduces GNOME 49, which includes innovative functionalities such as controlling media and power directly from the lock screen and improved HDR brightness settings for a richer viewing experience. Additionally, Ubuntu 25.10 aligns with the European Accessibility Act by enhancing accessibility options.
A couple of exciting new applications are part of this release: Loupe, a modern image viewer designed as a user-friendly alternative to traditional media applications, and Ptyxis, a lightweight terminal emulator prioritizing user convenience.
Built on the robust Linux 6.17 kernel, Ubuntu 25.10 brings significant advancements, including the capability to run virtual machines within virtual machines on Arm processors, initial support for Intel's TDX secure computing technology, and enhanced full disk encryption through TPM-backed solutions featuring passphrase support and recovery key management. Security is further strengthened with Network Time Security (NTS) activated by default, ensuring synchronized time across all systems.
The developer experience has seen notable improvements with updated toolchains for Python 3.13.7, Python 3.14 RC3, GCC 15, Rust 1.85, Go 1.25, OpenJDK 25, and previews of .NET 10 and Zig. Rust-based versions of core utilities, such as sudo, enhance memory safety and system stability. The new RVA23 profile is also introduced as the standard for RISC-V systems, laying the groundwork for future Long-Term Support (LTS) releases like Ubuntu 26.04.
In conjunction with the main release, several official Ubuntu flavors were also launched, including Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu. Each of these flavors will receive maintenance updates for nine months.
Users can easily download Ubuntu 25.10 from the official download page at https://ubuntu.com/download. For those currently running Ubuntu 25.04 and opted for notifications on all releases, an automatic upgrade to version 25.10 is available. It is advisable for users to review the release notes for any known issues and workarounds, which can be found at https://discourse.ubuntu.com/t/questing-quokka-release-notes/59220.
In conclusion, Ubuntu 25.10 not only embodies Ubuntu's commitment to innovation and community collaboration but also enhances usability, accessibility, and security, reaffirming its place as a leading choice for users seeking a reliable Linux distribution.
