Checksum e date di osservazione

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.

2.22.3-1-1 / 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: 5d4202de81f28cfc82df989fe9634f941e777e782f69a035bc7db11c8d6062d2

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

printf '%s %s\n' '5d4202de81f28cfc82df989fe9634f941e777e782f69a035bc7db11c8d6062d2' 'libnccl2_2.22.3-1-1_amd64.deb' | sha256sum --check --strict -

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