Ubuntu 26 generally available and latest migration
By Steven Van ·
GitHub Actions' ubuntu-latest label moves from 24.04 to 26.04 between October 19 and November 19, 2026, with 24.04 still available by pinning.
The Ubuntu 26.04 runner image for GitHub Actions is now generally available for production workflows on both x64 and arm64. Workflows can target it directly with runs-on: ubuntu-26.04 or ubuntu-26.04-arm.
The ubuntu-latest label will also move from Ubuntu 24.04 to Ubuntu 26.04, rolling out gradually between 19 October and 19 November 2026. Because tool and package versions differ between the two releases, this can break workflows that depend on specific versions or preinstalled software. Workflows not ready for the change can pin to ubuntu-24.04 to stay on the current image.
