Ubuntu 26.04.1 LTS Resolute Raccoon is a point release that consolidates fixes and improvements for the 26.04 LTS baseline and is offered as the recommended upgrade for Ubuntu 24.04 LTS users. The desktop integrates GNOME 50 and a full embrace of Wayland, delivering smoother visuals, per‑monitor fractional scaling, native touch and gesture support, variable refresh rate, and reduced screen tearing. A modernized default app set (Papers, Loupe, Ptyxis, Resources) and broad accessibility fixes accompany a unified App Center that shows debs and snaps side‑by‑side. For developers and AI practitioners, the release bundles up‑to‑date toolchains (Python, Rust, Go, Ruby, PHP, Perl) and popular ML frameworks (TensorFlow, PyTorch, Keras, OpenCV, Kubeflow). Notably, NVIDIA CUDA is now distributed natively from Ubuntu repositories, NVIDIA DOCA‑OFED is available via an official PPA, and AMD ROCm is included for accelerated workloads. Workshop enables one‑command sandboxed, composable development environments.

Enterprise and security enhancements focus on hardening and long‑term support. TPM‑backed full‑disk encryption is generally available in the installer and the new Security Center centralizes TPM, Secure Boot, recovery, and disk protection management. Several core components are being reimplemented in memory‑safe Rust (kernel drivers, sudo‑rs, uutils coreutils), cryptographic defaults adopt hybrid post‑quantum key exchange and retire legacy ciphers, and confidential computing support covers Intel TDX and AMD SEV. Canonical extends Livepatch to Arm64, updates WSL with cloud‑init and Ubuntu Pro, and offers Ubuntu Pro for up to 10 years of expanded package coverage (plus an optional 5‑year Legacy Support add‑on), positioning 26.04.1 LTS for both new deployments and enterprise fleets.
