Intel NPU Driver v1.38.0 Brings Ubuntu 26.04 LTS Support and Major Component Upgrades
Intel has pushed Linux NPU Driver v1.38.0 to the main repository. The drop landed today and it finally gives you official support for Ubuntu 26.04 LTS across every current NPU platform.
If you are running Meteor Lake, Arrow Lake, Lunar Lake, Panther Lake, or Wildcat Lake, this is the build you will want to install. The driver now targets kernel 7.0.0-31-generic, which means it has to move along with the OS release train. The jump from kernel 6.17 to 7.0 is not just a number. It is a whole new foundation, and Intel has aligned the NPU driver to match the OS release cadence.
What Is Actually in v1.38.0
The headline feature is the Ubuntu certification, but the underlying stack got a serious refresh. Level Zero jumped from 1.28.2 to 1.32.0. OpenVINO moved from 2026.2 to 2026.3.1. The bundled NPU compiler, now labeled UD2026.38 or version 8.3.0, was released separately on September 2 and covers all five silicon generations. You will also notice the GPU driver moved to 26.31.39395.13 from the kobuk-team PPA.
The NPU compiler itself includes Sigstore Cosign signatures and immutable GitHub release attestations. If you care about supply chain security, that is one less thing to worry about when pulling down binary blobs.
Testing Numbers and What They Mean
Intel ran the full UMD test suite against Ubuntu 26.04 on kernel 7.0.0-31, and the results are clean. Zero failures across the board.
The newer silicon pulls ahead in pass rates. Lunar Lake, Panther Lake, and Wildcat Lake cleared 98 percent of the extended extend.yaml test suite. Meteor Lake and Arrow Lake lag behind at 83 percent. The missed tests on the older platforms mostly involve GPU co-testing and a handful of standard UMD checks.
The extend.yaml workload pushes ResNet50 for image classification and YOLOv8s for object detection through multi-inference pipelines. It tests real model graphs against target FPS numbers. Not a synthetic benchmark.
The driver ships as distribution-specific tarballs. You will grab linux-npu-driver-v1.38.0.20260910-34487311128-ubuntu2404.tar.gz for the current LTS or the 26.04 variant for the upcoming release. The process is straightforward. Purge the old intel-driver-compiler-npu, intel-fw-npu, and intel-level-zero-npu packages, extract the tarball, and run sudo dpkg -i *.deb. You will need to install libtbb12 as a dependency and grab the libze1 Level Zero loader from the PPA snapshot. Keep in mind that Ubuntu 26.04 LTS is still rolling out, so you might run into package conflicts on a fresh install. A reboot and a quick add-to-render-group touchup, and you are done.
Intel tracks these drops by unified week. v1.38.0 falls in WW38 of 2026, fitting into a quarterly cadence that has been rolling out updates since December 2025. Keep an eye on the GitHub release page if you want to track the next iteration. The repo sits at 453 stars with 22 open issues, and the team is clearly moving faster than the kernel version numbers suggest.
