Ubuntu 26.04: Release Date and New Features in Resolute Raccoon

Ubuntu 26.04 LTS release date is April 23, 2026. This is the next long-term support release scheduled after Ubuntu 24.04 LTS, providing five years of standard support with extended maintenance available through Ubuntu Pro for up to 10 years total.

Release Information

Ubuntu 26.04 LTS, codenamed Resolute Raccoon, is scheduled for release on April 23, 2026. The codename was chosen by Steve Langasek, a former Debian and Ubuntu release manager who passed away in early 2025. The name “Resolute” reflects determination and unwavering commitment, fitting qualities for an LTS release that millions will depend on for years.

Ubuntu 26.04 Desktop requires a 2 GHz dual-core processor, a minimum of 6GB RAM (raised from the previous 4GB), and 25GB of free disk space. The increased memory requirement reflects the demands of the modern GNOME 50 desktop and Wayland session.

This release date holds special significance in Ubuntu history as the most common release date, shared with Ubuntu 9.04, 15.04, and 20.04 LTS. The first point release, Ubuntu 26.04.1, is scheduled for August 6, 2026, this is when Canonical typically enables direct upgrades from the previous LTS (24.04).

Development Timeline

Ubuntu 26.04 LTS follows a structured development cycle with clearly defined milestones. The complete official release schedule is available on Ubuntu Discourse.

Ubuntu published four monthly snapshot releases during the development cycle. Snapshot 1 was released on November 27, 2025, with Snapshot 2 in early December 2025, Snapshot 3 on January 29, 2026, and Snapshot 4 on February 26, 2026 as the final snapshot before the beta release on March 26, 2026.

Key Features

According to the official Ubuntu 26.04 LTS Roadmap, this release focuses on stability, refinement, and enhanced user experience. Key features include:

1. GNOME 50 Desktop Environment: Ubuntu 26.04 LTS ships with GNOME 50, which removes the GNOME-on-X11 session. The GNOME desktop now runs exclusively on Wayland, while XWayland remains available for legacy X11 applications. Note that this affects only the GNOME session — other desktop environments such as KDE Plasma and Xfce continue to support X11 sessions. New GNOME 50 features include fractional scaling improvements, autostart app management in Settings, remote desktop hardware acceleration (Vulkan and VAAPI), improved VRR support, enhanced Orca accessibility with a new Reduced Motion option, and parental controls with screen time limits.
2. Rust-Based Core Utilities: The distribution adopts memory-safe Rust implementations as defaults:
   • sudo-rs (0.2.12): Rust implementation of the sudo command, configured as the default via alternatives. The traditional sudo package remains installed as a fallback (sudo.ws).
   • uutils/coreutils (0.7.0): Rust-based core utilities (ls, cp, mv, etc.) replacing GNU coreutils as the default. GNU coreutils remain available and users can switch between them.
3. Wayland Enhancements: This release marks Ubuntu’s transition to a Wayland-only GNOME session. Ubuntu 26.04 includes Mutter patches that significantly improve NVIDIA graphics performance under Wayland, reducing blocked frame time from milliseconds to microseconds.
4. x86-64-v3 Packages: Optional amd64v3 package variants are available for newer CPUs, offering modest average performance improvements (~1%) with larger gains for numeric workloads. A mass archive rebuild ensures all packages are compiled with appropriate optimizations. Important: systems using amd64v3 packages cannot be moved back to older CPUs lacking x86-64-v3 support without recovery steps.
5. Unified Software Management: App Center becomes the single place to handle all applications regardless of packaging format. This includes fully managing DEB packages directly in App Center and the removal of “Software & Updates” (software-properties) from default installs — it remains installable via apt for users who need it. Note that Flatpak support in App Center is not planned for the initial 26.04 release; the near-term focus is closing the gap in DEB package management.
6. AMD ROCm Native Packages: Canonical is partnering with AMD to provide native ROCm packages directly in Ubuntu repositories, alongside NVIDIA CUDA, simplifying GPU setup for AI and machine learning workloads.
7. Technical Updates: The toolchain includes Linux Kernel 7.0 (originally targeted as 6.20, renumbered upstream), Mesa 26.0 graphics drivers, Python 3.14 (default on current builds; official LTS summary references 3.13.9 with 3.14 available), GCC 15.2 (default; GCC 16 available as optional toolchain), OpenJDK 25 (default; LTS lines 8/11/17/21 remain available), Golang 1.26, LLVM 21, glibc 2.43, Rust 1.93, and binutils 2.46. The monolithic linux-firmware package has been split into smaller component packages (e.g. linux-firmware-intel-wireless, linux-firmware-nvidia-graphics, linux-firmware-realtek) to reduce routine update download sizes.
8. JPEG XL Support: The JPEG XL image format is now supported out of the box without needing to install additional packages.
9. Crash Dumps Enabled by Default: The linux-crashdump and kdump-tools packages are now installed by default on both desktop and server installations, making it easier to diagnose kernel issues.
10. Windows Gaming Performance: The ntsync driver emulates Windows NT synchronization primitives, delivering better performance for Windows games running on Wine and Proton (Steam Play).
11. GStreamer 1.28: The multimedia framework has been updated to 1.28, improving playback, encoding, and streaming capabilities across the desktop.
12. Netplan 1.2: Updated from Netplan 1.0, bringing improved wait-online behavior, routing policy support, and better OVS/SR-IOV integration for network configuration.

System Infrastructure

Ubuntu 26.04 LTS includes several significant changes to core system infrastructure that administrators and advanced users should be aware of:

1. systemd 259: Ubuntu 26.04 ships with systemd 259, which removes cgroup v1 support entirely. Only the unified cgroup v2 hierarchy is supported. This is the most operationally disruptive change in this release: Ubuntu installations still running cgroup v1 will not be allowed to upgrade to 26.04 LTS, and container workloads that require cgroup v1 will not run on 26.04 hosts. Administrators should verify cgroup v2 readiness before planning upgrades. Additionally, Ubuntu 26.04 LTS is the last release supporting System V service script compatibility in systemd — services should be migrated to native systemd unit files.
2. Dracut Initramfs: Ubuntu now uses Dracut as its default initramfs generator, replacing initramfs-tools. Dracut addresses several limitations of the previous tool, including better NVMe-over-Fabrics support and reduced fragile early-boot shell code. The initramfs-tools package remains available in the repositories for users who need it.
3. APT 3 Series: The package manager has been updated to APT 3.1, bringing a new dependency solver that activates automatically when the classic solver fails, and a switch from GnuTLS/gcrypt to OpenSSL for TLS connections. Notably, apt-key has been removed — signature verification now uses gpgv directly. Administrators relying on apt-key in scripts will need to update their workflows.
4. /tmp is tmpfs by Default: The /tmp directory is now mounted as tmpfs (RAM-backed) by default, following upstream systemd conventions. This improves performance for temporary file operations but means /tmp contents are limited by available RAM and do not persist across reboots. Workloads that write large temporary files to /tmp may need adjustment.
5. Removable Media Mount Point: Removable media mount points have moved from /media to /run/media, aligning with upstream conventions and read-only rootfs requirements. Scripts or configurations referencing /media paths may need updating.
6. Chrony Default Time Daemon: Chrony replaces systemd-timesyncd as the default time synchronization daemon for new installations, providing more robust NTP synchronization including Ubuntu-specific NTP pool handling.
7. “Software & Updates” Removed from Default Installs: The software-properties-gtk package (“Software & Updates”) has been removed from default desktop installs to reduce confusing overlapping GUI entry points. Advanced workflows remain available via CLI, and the tool can be reinstalled from the archive.

Security & Encryption

Security improvements are a major focus for Ubuntu 26.04 LTS:

1. TPM-Backed Full Disk Encryption: Building on work from Ubuntu 25.10, TPM-backed FDE reaches general availability with new features including the ability to add/remove PIN or passphrase after installation and re-encrypt disks directly from the Security Center.
2. Snap Permissions Prompting: The Prompting Client will be enabled by default, providing a granular permissions framework that prompts users when Snap applications attempt to access restricted resources like hardware features or filesystem locations.
3. Intel TDX Confidential Computing: Native support for Intel Trust Domain Extensions creates secure, isolated virtual machines using AES-128 hardware encryption for confidential computing workloads.
4. Post-Quantum Cryptography: Updated OpenSSH and OpenSSL packages with hybrid post-quantum algorithms by default (X25519+ML-KEM for TLS, mlkem768x25519-sha256 for SSH), providing quantum resistance while maintaining backward compatibility.
5. sudo-rs Password Feedback: The sudo-rs implementation now shows asterisks when typing a sudo password by default, consistent with modern password prompts. Users who prefer the classic silent input can revert this via visudo by adding Defaults !pwfeedback.
6. AppArmor Profiles Expansion: The AppArmor package now includes many new profiles for applications as part of an ongoing effort to improve system-wide sandboxing. These profiles may cause breakage for unanticipated use cases — users are encouraged to report issues on Launchpad.
7. Ubuntu Insights: Ubuntu Insights replaces Ubuntu Report as the system metrics reporting tool. The metrics collection is opt-in, and prior consent from Ubuntu Report does not carry forward. New graphical controls in Settings allow fine-grained management of telemetry consent.

Hardware Support

Ubuntu 26.04 ships with Mesa 26.0, providing enhanced graphics drivers with Vulkan 1.4 support and improved GPU optimizations across Intel, AMD, and NVIDIA hardware.

Intel Arc and Battlemage GPU Support: This release brings full support for Intel Core Ultra Xe2 integrated Arc graphics and Intel Arc B580/B570 “Battlemage” discrete GPUs, including improved ray tracing performance and additional hardware-accelerated encode formats.

NVIDIA Improvements: NVIDIA Dynamic Boost is enabled by default on supported laptops, dynamically shifting power between CPU and GPU depending on workload. Canonical has also committed to distributing NVIDIA CUDA directly in Ubuntu starting with 26.04. However, the official known-issues documentation still warns of suspend/resume visual corruption and freezes on NVIDIA desktops under the default Wayland session. Users experiencing this issue may need to select “Ubuntu on Xorg” as a workaround where available, or wait for post-release SRU fixes.

Qualcomm Snapdragon Support: The release includes support for Qualcomm Snapdragon laptops through Stubble, a minimal UEFI kernel boot stub for loading machine-specific device trees with Secure Boot compatibility.

Raspberry Pi A/B Booting: A/B booting support for Raspberry Pi provides automatic fallback to known-good configurations if boot updates fail.

Dual Boot Enhancements: Improved dual boot experience with BitLocker-protected Windows systems, including the ability to install alongside existing BitLocker partitions when space is available, and exposing encrypted installation and other advanced options in dual-boot flows.

Accelerated Video Encoding/Decoding: When enabling third-party software during installation, video encoding and decoding is hardware-accelerated via VA-API for supported hardware, enabling full-framerate screen recording.

Default Applications

Ubuntu 26.04 introduces a number of changes to default applications accumulated since Ubuntu 24.04 LTS, bringing a more modern and consistent experience:

• Papers (50.0): Replaces Evince as the default PDF viewer; built on the Evince codebase but updated to GTK4 and partially rewritten in Rust
• Loupe: Replaces Eye of GNOME (EOG) as the default image viewer; written in Rust and powered by the Glycin library
• Ptyxis (50.1): Replaces GNOME Terminal as the default terminal emulator
• Sysprof: Now installed by default as a system performance profiling utility
• GIMP 3.2: Major update from version 2.10, bringing significant improvements to the default image editor
• Resources (1.10.2): Replaces GNOME System Monitor for process management and hardware monitoring, chosen for its superior accessibility support
• Showtime: Planned to replace Totem as the default video player (pending confirmation in final release — not present in current pre-release builds)

Replaced applications remain available in the Ubuntu archives for users who prefer them.

Support Lifecycle

As an LTS release, Ubuntu 26.04 receives comprehensive long-term support:

• Standard Support: 5 years until April 2031 (security patches and bug fixes)
• Hardware Enablement: 3 years of HWE kernel updates
• Expanded Security Maintenance: Additional 5 years through Ubuntu Pro, for a total of 10 years until April 2036

Testing & Downloads

Monthly Snapshots: Four monthly snapshots were published during the development cycle. Snapshot 4, released February 26, 2026, was the final snapshot before the beta.

Beta Testing: The official beta was released on March 26, 2026. Beta images are available from releases.ubuntu.com (x86) and cdimage.ubuntu.com (all architectures). The beta is reasonably free of showstopper bugs and representative of the features intended for the final release.

Daily Builds: Development ISO images are available for testing via the Ubuntu 26.04 download page.

Ubuntu 26.04 LTS will be available on April 23, 2026. In the meantime, users can continue using Ubuntu 24.04 LTS which receives support until April 2029.

Technical updates include Linux kernel 7.0, Mesa 26.0, Python 3.14, GCC 15.2, OpenJDK 25 (default), Golang 1.26, LLVM 21, and glibc 2.43.
2. How long will Ubuntu 26.04 LTS be supported? Standard support lasts 5 years until April 2031. With Ubuntu Pro (free for personal use on up to 5 machines), you can extend support via ESM for an additional 5 years, for a total of 10 years until April 2036.
3. When can I upgrade from Ubuntu 24.04 LTS? Direct upgrades from Ubuntu 24.04 LTS are typically enabled with the first point release. Ubuntu 26.04.1 is scheduled for August 6, 2026, which is when the upgrade path will officially open.
4. Why is Ubuntu switching to Rust-based utilities? Ubuntu adopts Rust-based utilities primarily for enhanced memory safety and resilience. Rust’s compiler prevents entire classes of memory-related bugs at compile time, reducing security vulnerabilities. The transition includes fallback options to traditional utilities for compatibility.
5. What is the difference between monthly snapshots and the beta release? Monthly snapshots are automated development builds representing work-in-progress code. The beta release (March 26, 2026) is a more stable milestone where major features are frozen and undergoes formal testing before release.
6. Will all Ubuntu flavors have LTS status? No. Ubuntu MATE and Ubuntu Unity will not have LTS status for 26.04 due to limited contributor resources. Other official flavors including Kubuntu, Xubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Studio, Edubuntu, and Ubuntu Kylin are proceeding with LTS status.
7. What happens to X11 in Ubuntu 26.04? GNOME 50 removes the GNOME-on-X11 session, but this does not affect the Xorg server itself or other desktop environments. KDE Plasma, Xfce, and other DEs continue to support X11 sessions. X11 applications also continue to work within GNOME via XWayland.
8. What is the cgroup v2 requirement? Ubuntu 26.04 requires cgroup v2 (unified hierarchy). Systems still using cgroup v1 cannot upgrade to 26.04, and container workloads requiring cgroup v1 will not run on 26.04 hosts. Verify your system with mount | grep cgroup — you should see cgroup2 on a compatible system.
9. What is Dracut and why did Ubuntu switch? Dracut is an initramfs generator that replaces the previous initramfs-tools. The switch addresses limitations including better NVMe-over-Fabrics support and reduced fragile early-boot shell code. The initramfs-tools package remains available in the repositories if needed.
