Ubuntu 26.04 LTS Desktop Welcome

Ubuntu 26.04 LTS (Resolute Raccoon) was released today in April 2026 (hence the “26.04”) with significant updates for server and infrastructure deployments.

Linux Kernel 7.0 and Hardware Enablement

The generic kernel stack upgrades from version 6.8 to Linux kernel 7.0, delivering improved hardware support and performance optimizations. A few of the highlights are:

Intel Panther Lake Support – Enhanced support for Intel Core Ultra Series 3 processors with targeted optimizations for Intel Xe3 integrated graphics and the integrated NPU (Neural Processing Unit)
EtherCAT Industrial Networking – Integrated IgH EtherCAT module and generic driver for real-time industrial Ethernet networks
Real-Time Kernel Availability – The PREEMPT_RT real-time kernel is now available in the main archive outside of Ubuntu Pro, following upstream integration
ARM64 Livepatch Support: Kernel Livepatch now supports ARM64 architecture for security patches without rebooting
Crash Dumps Enabled by Default: Kdump is enabled by default for desktop and server installations
Sched_ext Support: New eBPF-based scheduling system allows user-space scheduler implementation

The lowlatency kernel package has been retired in favor of linux-generic, combined with the user-space lowlatency-kernel package for…
