Use this package OpenFactory can boot this operating system in a browser VM, or start a build that includes the native package name from this record.
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.
4.12.1-2 / all Observed 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: 156f478194fd936f20955c16d2b6135bc2ccf42e481252de4328693f96189e6a
After downloading that exact artifact, compare its bytes with the source-reported expected digest:
printf '%s %s\n' '156f478194fd936f20955c16d2b6135bc2ccf42e481252de4328693f96189e6a' 'gap_4.12.1-2_all.deb' | sha256sum --check --strict -A match establishes equality with the repository metadata value. It does not establish safety or catalog-side artifact retrieval.

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.
Authoritative source; repository metadata signature verified, revision bookworm-main-amd64:9e0b5aabb2465b3d2e7a7fe27f9913846277833f7a2826e7767acccff5b588c5
Signature verification covers the configured repository metadata chain. It does not certify that the package is safe or suitable.
