Validate, promote, build, sign, test, or publish Nebula Linux DEB releases through the public signed APT repository. Use for BerylliumSec/nebula-apt, stable or prerelease APT channels, archive signing keys, GitHub Pages deployment, package install or upgrade testing, and changes to packaging/repositories/nebula-apt.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Release Nebula APT Use `packaging/RELEASING.md` as the release contract and `packaging/repositories/nebula-apt` as the external repository scaffold. Treat release tags, published assets, attestations, and promoted channel entries as immutable. ## Guardrails - Accept only a published `nebula-v3.*` release and its `Nebula-VERSION-linux-x86_64.deb`. - Map semantic versions with a prerelease suffix only to `prerelease`; map versions without one only to `stable`. - Verify the release-provided SHA-256 and GitHub provenance attestation before changing `channels.json`. Match the checksum filename exactly; similarly prefixed SBOM filenames are separate assets. - Validate `Package`, `Version`, and `Architecture` from DEB metadata. Do not pass `--arch` to `dpkg-scanpackages`: Nebula's managed asset ends in `linux-x86_64.deb`, while that option filters Debian-style filenames ending in `_amd64.deb`. - Retain the current and previous package in each channel so CI tests a real upgrade. - Require every promotion to advance semantic-version precedence. Reject downgrades, duplicate versions, and any change to an already-recorded tag. …

How to install
mdr add berylliumsec/nebula/release-nebula-apt@sha256:4d8a29df840aa9feThe line at the top of this page pins the label git:20260726.8c49c67, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
