Ubuntu Livepatch now on Arm64—no more reboots for kernel updates

bekir June 23, 2026 3 min read 45 views

Canonical has unveiled that its Livepatch service now extends support to machines powered by Arm64 processors. Livepatch lets users apply critical kernel updates on the fly, eliminating the need for costly reboots or downtime—a boon for both everyday consumers and mission‑critical systems that cannot afford interruptions.

Analysis: By enabling seamless kernel updates on Arm64, Canonical taps into the growing demand for zero‑downtime security patches in edge and IoT deployments, positioning Ubuntu as a resilient choice for enterprises navigating the Cyber Resilience Act.

The new capability ships with Ubuntu Core 26 for Arm64, while Ubuntu Core 20 and later versions remain available for AMD64. Canonical emphasizes that this enhancement bolsters security for devices that aren’t updated daily or weekly, aiding organizations in meeting Cyber Resilience Act compliance requirements.

For those familiar with Ubuntu, most software packages can be refreshed without rebooting. The kernel, however, traditionally forces a system restart to load the new version. Livepatch removes that hurdle, allowing the kernel to be patched in real time.

Connecting your machine to Ubuntu Pro doubles the support horizon for your Ubuntu installation—from five years to a full decade—giving users a longer, more secure platform without the hassle of frequent upgrades.

If you’re an Ubuntu user, share in the comments whether you’ve been looking forward to this feature on your ARM device. And if you own a compatible AMD64 system but haven’t taken advantage of it yet, let us know why.
