Overview
- Canonical released Ubuntu 26.04 LTS, codenamed Resolute Raccoon, with standard security updates promised through April 2031.
- More of the OS now uses memory‑safe Rust, including new kernel drivers plus Rust versions of core tools like sudo and coreutils, which reduces common bugs that lead to security flaws.
- Full‑disk encryption in the installer now supports Trusted Platform Module binding, which locks the drive to the device’s TPM chip and removes the need to type a passphrase at boot.
- Kernel Livepatch now covers Arm64 servers for the first time, which lets operators fix critical kernel issues without reboots on Arm hardware used for always‑on workloads.
- Ubuntu’s own repositories now distribute NVIDIA CUDA and add AMD ROCm, which lets teams install and update AI and HPC GPU stacks through standard Ubuntu packages with LTS support.
