Deep Dive Topic - Ubuntu 26.04 LTS Resolute Raccoon

• Canonical released Ubuntu 26.04 LTS “Resolute Raccoon” on April 23, 2026, marking a significant modernization of the distribution with GNOME 50 and the Linux kernel 7.0. This LTS version offers five years of standard support until April 2031, extending to ten years with Ubuntu Pro.
  • Key updates include:
    • Wayland-Only Desktop: The GNOME session now runs exclusively on Wayland, dropping Xorg support, though X11 applications remain functional via XWayland.
    • Enhanced Security: The release introduces TPM-backed full-disk encryption, post-quantum cryptography support in OpenSSL, and the Security Center app for desktop management.
    • New Default Applications: Canonical replaced legacy tools with modern GTK4/libadwaita apps, including Ptyxis (terminal), Papers (PDF), Loupe (images), Showtime (video), and Resources (system monitor).
    • Developer & Server Improvements: The toolchain features GCC 15.2 and Python 3.14, while server editions support Intel TDX and AMD SEV-SNP confidential computing.
    • Hardware Requirements: The recommended minimum RAM has increased to 6 GB to accommodate the modern desktop environment.
