The host .deb was built on the Ubuntu 26.04 rust-ci image, so dpkg-shlibdeps baked in `Depends: libavcodec62` (FFmpeg 8) and a glibc-2.41 floor — making it uninstallable on Ubuntu 24.04 LTS (FFmpeg 6.1 / libavcodec60, glibc 2.39; apt reports the deps as "too recent"). The source floor (ffmpeg-next 8, libavcodec >=61 APIs) means a straight 24.04 rebuild would fail too. Build the host on Ubuntu 24.04 instead — lowering the glibc floor to 2.39 so one binary runs on 24.04 -> 26.04 — and bundle a from-source LGPL FFmpeg 8 into the package so it no longer depends on the distro libav*. Everything else the host links is soname-compatible on 24.04 (opus is vendored via cmake; NVENC/libcuda are dlopen-only, never link-time), and the only FFmpeg encoders used are *_nvenc / *_vaapi (software H.264 fallback is the BSD-2 openh264 crate, not FFmpeg libx264), so an LGPL build keeps the bundle license-clean. - ci/rust-ci-noble.Dockerfile (new): ubuntu:24.04 builder; nv-codec-headers + FFmpeg 8 (--enable-nvenc --enable-vaapi, shared) -> /opt/ffmpeg; PKG_CONFIG_PATH. - packaging/debian/build-deb.sh: BUNDLE_FFMPEG=1 copies libav*/libsw*/libpostproc into /usr/lib/punktfunk-host, patchelf-sets the rpath ($ORIGIN per-lib + binary --force-rpath), feeds them to dpkg-shlibdeps (captures libva2/libdrm2), and drops the libav* sonames from Depends. Normal (non-bundle) path unchanged. - .gitea/workflows/deb.yml: split into build-publish (client/web/scripting on the 26.04 image) and build-publish-host (noble image, BUNDLE_FFMPEG=1); parallel, identical version step, same apt distribution -> one universal host .deb. - .gitea/workflows/docker.yml: build+push punktfunk-rust-ci-noble. - packaging/debian/README.md: document the 24.04 LTS path + bundled local build.

# LTS builder for the punktfunk HOST .deb — Ubuntu 24.04 (noble), the current Ubuntu LTS.
|
|
#
|
|
# WHY THIS EXISTS (see packaging/debian/README.md → "Ubuntu 24.04 LTS"):
|
|
# The default builder (ci/rust-ci.Dockerfile) is Ubuntu 26.04, so the host .deb it produces bakes
|
|
# in a glibc 2.41 floor and a hard `Depends: libavcodec62, …` (FFmpeg 8). Ubuntu 24.04 LTS ships
|
|
# glibc 2.39 and FFmpeg 6.1 (libavcodec60), so that .deb is uninstallable there — apt reports the
|
|
# deps as "too recent". Building the host on 24.04 instead lowers the glibc floor to 2.39 (the
|
|
# binary then runs on 24.04 → 26.04), and the ONE library 24.04 is too old for — FFmpeg — is built
|
|
# from source here and BUNDLED into the .deb (packaging/debian/build-deb.sh, BUNDLE_FFMPEG=1), so
|
|
# the package no longer depends on the distro's libav* at all. Everything else the host links
|
|
# (PipeWire, Wayland, xkbcommon, GL/EGL/GBM, Vulkan; opus is vendored via cmake) is soname-compatible
|
|
# on 24.04, so this ONE universal host .deb replaces the 26.04-built one for every Ubuntu user.
|
|
#
|
|
# libcuda is deliberately NOT provided: the host dlopen's libcuda.so.1 at runtime (pf-zerocopy /
|
|
# pf-encode) and never link-imports it, so — unlike the full-workspace rust-ci image, which builds
|
|
# tests that DO link a cuda stub — this host-only build needs no NVIDIA driver package. NVENC/EGL
|
|
# come from whatever driver the target runs, out of band.
|
|
#
|
|
# Rebuilt+pushed by .gitea/workflows/docker.yml (matrix: punktfunk-rust-ci-noble); consumed by the
|
|
# `build-publish-host` job in .gitea/workflows/deb.yml. Bootstrap: like rust-ci, the first deb.yml
|
|
# run after this image is added uses the image from a PRIOR docker.yml push — seed it once manually
|
|
# (docker build -f ci/rust-ci-noble.Dockerfile -t … ci && docker push) before the host job can run.
