Sumas de comprobación y fechas de observación

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.

1:5.12.0+dfsg-2 / amd64Observed 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: 1de1de751a5f760073aab29bbd2c8a6f1c626d9d1f6b6b48071b6aa03833e508

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

printf '%s %s\n' '1de1de751a5f760073aab29bbd2c8a6f1c626d9d1f6b6b48071b6aa03833e508' 'libspqr2_5.12.0+dfsg-2_amd64.deb' | sha256sum --check --strict -

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