WalkthroughThis PR upgrades GitHub Actions workflows to run on Ubuntu 26.04 instead of 24.04. The box workflow's build job now configures packer with a TMPDIR environment variable, the test job adds libvirt-daemon-driver-interface as a dependency, and the CI workflow's setup job is updated to the newer runner.

setup-hashicorp-repo/action.yml(lines 1-18) derives the HashiCorp APT “dists” codename fromlsb_release -cs; the APT verification approach should not assumelsb_releaseis present—ensure the action/runner can obtain the codename (or switch to parsing/etc/os-release).

GitHub Actions hosted runner ubuntu-26.04 label available
💡 Result:
As of June 12, 2026, the Ubuntu 26.04 runner image is available for GitHub-hosted runners as a public preview [1][2]. You can use the following labels in your workflow configuration to select these runners: - ubuntu-26.04: For the x64 architecture [1][2]. - ubuntu-26.04-arm: For the arm64 architecture [1][2]. These images were announced as available for all GitHub Actions users on June 11, 2026 [3][2]. They are compatible with both standard and larger runners [2]. As this is a public preview, you may encounter differences in tools and software versions compared to older runner images [2]. Users are encouraged to check the official actions/runner-images repository for specific software manifests [2].

actionlint ubuntu-26.04 known runners update
💡 Result:
As of June 12, 2026, Ubuntu 26.04 and Ubuntu 26.04 Arm have been released as public previews for GitHub Actions [1]. While these images are available for use in workflows, actionlint does not yet natively recognize ubuntu-26.04 or ubuntu-26.04-arm as standard, pre-defined runner labels in its built-in configuration (which currently prioritizes labels up to Ubuntu 24.04 and macOS 26) [2][3]. If you use runs-on: ubuntu-26.04 or runs-on: ubuntu-26.04-arm in your GitHub Actions workflows, actionlint may report these as unknown runner labels. You can resolve this by adding them to your actionlint configuration file (actionlint.yaml) to inform the tool that these are valid labels for your environment [4][3]. To configure actionlint to recognize these labels, add the following to your actionlint.yaml file: runner-label: - ubuntu-26.04 - ubuntu-26.04-arm This will suppress the unknown label error during static analysis [4][3]. Note that GitHub's official runner software has been updated to support these new Ubuntu 26.04 dependencies [5], but actionlint's internal list of known labels is updated periodically through community contributions and repository releases [6][2][7].

Adjust actionlint handling for ubuntu-26.04 (runtime likely OK)
.github/workflows/box.yml uses runs-on: ubuntu-26.04 in both the build job (line 48) and test job (line 109). GitHub-hosted ubuntu-26.04 runners are available in public preview, so this should not inherently cause immediate workflow failure from runner unavailability. The likely blocker is static analysis: current actionlint versions may still flag ubuntu-26.04 as an unknown runner label unless the tool is updated or configured (e.g., via runner-label).
