Verify the directory notes

The SHA256SUMS manifest lists the text notes included in this mirror. Download those files with their relative directories intact, then run the appropriate command from your local mirror directory.

Linux with GNU coreutils

sha256sum -c SHA256SUMS

macOS

shasum -a 256 -c SHA256SUMS

Each listed file should report OK. Missing files cannot be verified. If a hash differs, do not use that copy; check that the file and manifest belong together.

For archived artifacts, use the checksum or signature stored with that artifact. The mirror’s directory-note manifest verifies only the text notes named in it.

Resume an interrupted download

A download client may resume an unchanged static file using a byte-range request. For curl, replace the placeholder below with the complete HTTPS link to the file:

curl --fail --location --continue-at - --remote-name 'FULL_HTTPS_FILE_URL'

Run it in the directory containing the partial download. When a file has changed, discard the partial copy and download it again. Verify the completed file.

A file is missing

Go back to the directory index and check the filename and letter case. Archived paths are static, but retained upstream material may be organized below project, version or architecture directories.
