Real-time Ubuntu
Run the most exacting workloads for
low-latency use cases with Real-time Ubuntu
Real-time Ubuntu ensures high-priority processes are executed first, with deterministic response times.
Why use Real-time Ubuntu?
- Support for real-time compute with PREEMPT_RT
- Time-bound for mission-critical latency requirements
- More preemptive than mainline Linux
- Up to 15 years of security maintenance

Real-time Ubuntu use cases
Industrial settings
PLCs in assembly lines must deliver and process data in real-time to ensure system integrity and continuous production.
Telco
Real-time Ubuntu brings ultra-low latency and enhanced security capabilities to telco workloads and the critical infrastructure they run on.
Healthcare robotics
From autonomous mobile robots to life-support medical equipment, healthcare systems must complete tasks within specified deadlines.
Automotive
Automotive manufacturers are increasingly reliant on real-time Linux for infotainment systems, HMIs and latency-sensitive scenarios.

What is Real-time Ubuntu?
Canonical and Intel collaborate to deliver real-time Ubuntu on 12th Gen Intel® Core™ processors with TSN and TCC Support. Explore how real-time Ubuntu benefits the IoT customers and market as a whole.
Getting started
With the PREEMPT_RT patches being fully upstreamed, the real-time kernel is freely available for everyone from the 26.04 release onwards. Simply use the command:
sudo apt install ubuntu-realtimeNeed earlier versions?
All previous releases of the real-time kernel are available via Ubuntu Pro, Canonical's enterprise security and compliance subscription. Ubuntu Pro is free for personal and small scale commercial use in up to 5 machines.
With an Ubuntu Pro subscription, launching the real-time kernel is as easy as:
pro attach
pro enable realtime-kernelRun Real-time Ubuntu on Intel hardware
Optimized Real-time Ubuntu is available on 12th Gen Intel® Core™ processors. Coupled with Intel® Time Coordinated Computing (Intel® TCC) and Time Sensitive Networking (IEEE TSN), the real-time kernel delivers industrial-grade performance to meet stringent latency requirements:
Intel-optimized Real-time Ubuntu is available on Intel SoCs via Ubuntu Pro:
pro attach
pro enable realtime-kernel --variant=intel-iotgRun Real-time Ubuntu on Raspberry Pi
Based on the upstream v6.8 kernel, the 24.04 release of Real-time Ubuntu includes optimized support for Raspberry Pi hardware. Discover the possibilities of optimized real-time compute with enhanced performance on Raspberry Pi 4 and 5:
