Drop Debian bullseye from the build matrix - #306
Merged

Conversation
Debian 11 reached end of life on 2026-08-31 and the bullseye-security
pool is being deleted while the index still advertises its packages, so
`apt-get install` in the bullseye Dockerfile fails on 8 packages,
including libssl-dev, libc-dev-bin, linux-libc-dev and perl:
docker run --rm --platform linux/amd64 debian:bullseye-20260824 \
sh -c 'apt-get update -qq && apt-get -y --no-install-recommends install \
autoconf dpkg-dev gcc gcc-9 g++ make libncurses-dev unixodbc-dev \
libssl-dev libsctp-dev wget ca-certificates pax-utils'
exits 100. The same install on bookworm-20260824 and trixie-20260824
exits 0. bullseye-security is not on archive.debian.org yet, so there is
nothing to repoint apt at.
Every OTP release now queues four bullseye builds that fail and retry on
the queue backoff forever. OTP 29.1 is the current one, reported as
BOB-15.
Dropping bullseye from builds/0 also removes it from the build request
form, which clamps its os_version options to the matrix, so the
bullseye clause in build_erlang_ref?/3 is unreachable and goes with it.
Per-arch bullseye tags older than 30 days become deletable by
DockerCleanup. The multi-arch manifests users pull are not pruned.
Fixes BOB-15

bullseye-securityInReleaseis dated Sat, 12 Sep 2026 and itsPackagesstill listsperl 5.32.1-4+deb11u5atpool/updates/main/p/perl/perl_5.32.1-4+deb11u5_amd64.deb, but a directory listing of that path on deb.debian.org now returns onlydeb12files.So
apt-get installatpriv/scripts/docker/erlang-debian-bullseye.dockerfile:6fails on 8 packages, includinglibssl-dev,libc-dev-bin,linux-libc-devandperl:exits 100. The same install on
debian:bookworm-20260824anddebian:trixie-20260824exits 0.bullseye-securityis not on archive.debian.org yet (404 on itsRelease, whilebullseyemain is 200), so there is nothing to repoint apt at. Dropping the security source instead leaves apt with held broken packages.Every OTP release now queues four bullseye builds (2 os_versions x 2 arches) that fail and retry on the 24h queue backoff cap forever. OTP 29.1 is the current one, reported as BOB-15: 29.1 published for trixie on Docker Hub at 11:01 UTC today, bullseye failed on both arches at 11:33.
Two consequences worth naming.
builds/0is what the build request form clamps its os_version options to, so bullseye disappears from the form and the bullseye clause inbuild_erlang_ref?/3becomes unreachable, removed here. AndDockerCleanupkeeps erlang per-arch tags whose os_version is still in the matrix, so per-arch bullseye tags older than 30 days become deletable; the multi-arch manifests users pull are not pruned.Fixes BOB-15
