Following the guide on https://gitlab.wikimedia.org/repos/data-engineering/airflow-devenv#build-and-upgrade-instructions, we are running into some errors preventing the deployment of the new package.
bullseye-backports reached End OF Life in August of 2025 which gives and error of E: The repository 'http://mirrors.wikimedia.org/debian bullseye-backports Release' does not have a Release file..
Tried checking which of the packages require bullseye-backports by running the pdebuild without the backport DIST=bullseye-wikimedia pdebuild option and got
The following packages have unmet dependencies:
pbuilder-satisfydepends-dummy : Depends: python3-poetry-core which is a virtual package and is not provided by any available package
Depends: pybuild-plugin-pyproject which is a virtual package and is not provided by any available package
Unable to resolve dependencies! Giving up...This implies that the packages depending on this are python3-poetry-core and pybuild-plugin-pyproject.
Tried using the bookworm packages from https://packages.debian.org/search?keywords=pybuild-plugin-pyproject and https://packages.debian.org/bookworm/python3-poetry-core as an alternative with APT_USE_BUILT=yes BUILDRESULT=/home/stevemunene/pydep/pybuild-plugin-pyproject_5.20230130+deb12u1_all.deb BUILDRESULT=/home/stevemunene/pydep/python3-poetry-core_1.4.0-4_all.deb DIST=bullseye pdebuild or APT_USE_BUILT=yes BUILDRESULT=/home/stevemunene/pydep DIST=bullseye pdebuild which also resulted in the same error.
This is actively blocking release of any new airflow devenv packages and improvements
