gh-152785: [WIP] Upgrade Ubuntu from 24.04 to 26.04 in GitHub Actions by vstinner · Pull Request #152717 · python/cpython

vstinner · 2026-06-30T23:39:43Z

Touch Python/getcompiler.c to trigger most GHA jobs.

This PR upgrades Ubuntu from 24.04 to 26.04 in GitHub Actions to check what breaks and to see if it would be possible to make some upgrade.

Issue: GitHub Action: upgrade LLVM, GCC, Java and Ubuntu #152785

"Check if generated files are up to date" job: sudo ./.github/workflows/posix-deps-apt.sh logs an error:

E: Unable to locate package lzma-dev

Later in the same job, make check-c-globals fails with:

Lint / lint (pull_request): Failing after 40s

It complains because it doesn't know ubuntu-26.04. Example:

  .github/workflows/build.yml:56:14: label "ubuntu-26.04" is unknown. available labels are "windows-latest", "windows-latest-8-cores", "windows-2025", "windows-2025-vs2026", "windows-2022", "windows-11-arm", "ubuntu-slim", "ubuntu-latest", "ubuntu-latest-4-cores", "ubuntu-latest-8-cores", "ubuntu-latest-16-cores", "ubuntu-24.04", "ubuntu-24.04-arm", "ubuntu-22.04", "ubuntu-22.04-arm", "macos-latest", "macos-latest-xlarge", "macos-latest-large", "macos-26-xlarge", "macos-26-large", "macos-26", "macos-15-intel", "macos-15-xlarge", "macos-15-large", "macos-15", "macos-14-xlarge", "macos-14-large", "macos-14", "self-hosted", "x64", "arm", "arm64", "linux", "macos", "windows". if it is a custom label for self-hosted runner, set list of labels in actionlint.yaml config file [runner-label]

Ubuntu 26.04 and Ubuntu 26.04 Arm is now available as a public preview

(*) Address sanitizer (ubuntu-26.04): "Set up GCC-10 for ASAN" fails with Package g++-10 is not available, but is referred to by another package.

The job requires GCC 10 because in 2023, Ubuntu provided GCC 9 by default which had a bug with vfork(). This is no longer needed on Ubuntu 26.04.

Summary:

Create this PR to try to upgrade Ubuntu 24.04 to Ubuntu 26.04 (Resolute) in GitHub Actions.
The llvm.sh script failed to install LLVM 20. https://apt.llvm.org/ shows that LLVM 20 is the default LLVM version on Ubuntu 26.04, so it should work. Anyway, I upgraded LLVM to LLVM 22, it works around the issue.
Android job: Gradle 8 is incompatible with Java 25 (it fails with What went wrong: 25.0.3 error). I downgraded Java to Java 17: same Java version than the default Java version on Ubuntu 24.04. I didn't test if Gradle 8 is compatible with Java 21. FYI Ubuntu 24.04 also supports Java 21 and Java 25, but uses Java 17 by default.
Lint job: I had to modify .github/actionlint.yaml to put ubuntu-26.04 and ubuntu-26.04-arm in the allow list. Without that, actionlint reported that these images don't exist.
Address sanitizer job: there is a specific step to install GCC 10. It fails on Ubuntu 26.04. But Ubuntu 26.04 uses GCC 15.2 by default which is way newer, and so the GCC 10 step is no longer needed.

This PR changes multiple things at once. I created other PRs to upgrade LLVM, GCC and Java to prepare this PR. See pull requests attached to #152785.

skirpichev · 2026-07-02T07:34:12Z

Probably, with 26.04 you can remove libmpdec workaround from .github/workflows/posix-deps-apt.sh.

…ctions Update .github/actionlint.yaml to allow ubuntu-26.04 and ubuntu-26.04-arm images.

No longer install build+install libmpdec-dev from tarball.

ubuntu-latest is currently Ubuntu 24.04.

vstinner · 2026-07-03T13:47:20Z

Currently, ubuntu-latest means Ubuntu 24.04.

So I replaced runs-on: ubuntu-latest with runs-on: ubuntu-26.04.

@hugovk: Do we want to keep runs-on: ubuntu-latest and get the newer Ubuntu as soon as it's deployed? There is a risk of getting new issues if Ubuntu is upgraded, no?

vstinner · 2026-07-03T14:04:18Z
