Description

Adds Debian Trixie (13) to the BuildDebPackages/TestDebPackages matrix in azure-pipelines.yml, mirroring the existing Bookworm entries added in #26690.

packages.microsoft.com/repos/azure-cli/dists/ currently only goes up to bookworm, so anyone on Debian 13 installing via the documented apt-repo method hits a missing Release file (#32069). This PR adds the CI build/test matrix entry needed to produce a trixie .deb, the same way #26690 added Bookworm support after Debian 12's release.

Note: merging this adds trixie to what CI builds/tests, but actually publishing it to packages.microsoft.com/repos/azure-cli/dists/trixie/ is a separate internal release step outside this repo — flagging that step needs to happen too for #32069 to be fully resolved.

Fixes #32069

History Notes

• Add Debian Trixie (13) to the CI build/test matrix, following the Bookworm precedent from [Packaging] Add Debian Bookworm support #26690.

Naga Nandyala (@naga-nandyala) could this be reviewed please? Trixie has been released for almost a year now, would be great to have azure-cli supported 🙏🏼

Live test skipped

⏭️ Skipping the live test for this revision because no new test file was added (tests/**/test_*.py).

The live-test pipeline runs only the test files a PR changes, so there is nothing to execute for this commit. This is informational — a regression test is encouraged where it makes sense, but not required. If a test file is added in a later commit, the live test will run automatically.
