Description

Remove Debian 11 Bullseye from the DEB package build and test matrices while retaining Debian 12 Bookworm coverage for AMD64 and ARM64.

Debian officially ended Bullseye LTS support on August 31, 2026:

Since September 4, the Bullseye security repository has repeatedly returned HTTP 404 for packages still referenced by its signed package index. This prevents the Bullseye package jobs from installing their build dependencies even after a successful apt-get update.

Testing Guide

  • Reproduced the failure in a fresh mcr.microsoft.com/mirror/docker/library/debian:bullseye container after deleting all cached APT lists: apt-get update exited 0 and downloading libicu67 exited 100 with HTTP 404.
  • Reproduced the same result with the official debian:bullseye image, ruling out an MCR-specific issue.
  • Installed the full build dependency set successfully with the retained Bookworm image.
  • Verified the pipeline contains no Bullseye matrix entries and retains both Bookworm build and test entries.
  • Ran git diff --check.
