Versions, suites, and repositories

Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.

Checksums and observation dates

For an APT source, signature verification authenticates the repository metadata chain and the Packages index containing this source-reported artifact digest. It does not certify package safety.

9.1.0+ds1-2 / arm64Observed Sep 1, 2026 to Sep 1, 2026

Verification status: Metadata observed; artifact bytes were not independently fetched or hashed by this catalog import. The digest below is source-reported.

Source-reported sha256: 7d4f191b968e33c491b252bae91b5f67737c01b8946bda98d1a13d4bac65a0f2

After downloading that exact artifact, compare its bytes with the source-reported expected digest:

printf '%s %s\n' '7d4f191b968e33c491b252bae91b5f67737c01b8946bda98d1a13d4bac65a0f2' 'libfmt9_9.1.0+ds1-2_arm64.deb' | sha256sum --check --strict -

A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.

Catalog record completeness

The completeness score measures metadata coverage, not software quality, security, compatibility, or suitability.

Sources and provenance

Field-source links above resolve here. Each source entry names the metadata publisher, trust tier, exact snapshot revision, signature result, and observation time; catalog-derived mappings are labeled separately.
