Audio: a headless host has no speakers, and on a LAN with AirPlay devices PipeWire picks a random HomePod as default — so desktop audio (which the host captures from the default sink's monitor) went to a HomePod over AirPlay instead of to the client, and there was no "Punktfunk" output to select. Ship a `punktfunk-sink.conf` (a `support.null-audio-sink` adapter — NOT the non-existent module-null-sink, which makes pipewire refuse to start) with high priority.session so it's the default; run-headless-kde.sh installs it and restarts pipewire once on first install. The host then captures its monitor and streams it. (Disable AirPlay sinks out of band: `dnf remove pipewire-config-raop`.) Input: the host's libei portal D-Bus connection goes stale when the compositor session restarts the portal under it, and the in-process reopen loop can't recover it (EIS setup keeps timing out) — only a full restart does. Add PartOf=punktfunk-kde-session.service so the host restarts with the session. Both verified live on the Fedora 44 KDE box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
punktfunk-host — Debian/Ubuntu package (apt)
punktfunk-host is published as a .deb to Gitea's Debian package registry in the public
unom org, so the Ubuntu hosts update with plain apt. CI (.gitea/workflows/deb.yml) builds
and publishes on every push to main (a rolling 0.0.1~ciN.<sha> build) and on v* tags
(a clean X.Y.Z).
Package layout mirrors the Fedora RPM (../rpm/punktfunk.spec): the host binary, the /dev/uinput
udev rule, the systemd user unit, headless session helpers, the example config, and the OpenAPI
doc. Runtime Depends are computed by dpkg-shlibdeps from the binary itself (built in the Ubuntu
26.04 rust-ci image, so the lib soname package names match the target). The NVIDIA driver
(libnvidia-encode / libEGL_nvidia / libcuda) is not a dependency — it's installed out of
band, like on the RPM side.
Install on a host (one-time)
The registry is public, so no apt auth is needed — just trust the repo's signing key:
sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://git.unom.io/api/packages/unom/debian/repository.key \
| sudo tee /etc/apt/keyrings/punktfunk.asc >/dev/null
echo "deb [signed-by=/etc/apt/keyrings/punktfunk.asc] https://git.unom.io/api/packages/unom/debian stable main" \
| sudo tee /etc/apt/sources.list.d/punktfunk.list
sudo apt update
sudo apt install punktfunk-host
Then, as the desktop user:
sudo usermod -aG input "$USER" # virtual gamepads (re-login to take effect)
mkdir -p ~/.config/punktfunk
cp /usr/share/punktfunk-host/host.env.example ~/.config/punktfunk/host.env # then edit
systemctl --user enable --now punktfunk-host
Updates
sudo apt update && sudo apt upgrade # picks up the newest published build
systemctl --user restart punktfunk-host # if the unit was already running
Build a .deb locally
VERSION=0.0.1 bash packaging/debian/build-deb.sh # -> dist/punktfunk-host_0.0.1_amd64.deb
Needs dpkg-dev (dpkg-shlibdeps, dpkg-deb). It builds the release binary first if missing.
Build it in the rust-ci image (or on an Ubuntu 26.04 box) so the resolved Depends match the
hosts; building on a GPU box is fine — the NVIDIA driver lib is filtered out either way.
