debsnap - retrieve old snapshots of Debian packages
debsnap [options] package [version]
debsnap [-h | --help] [--version]
debsnap is a tool to help with retrieving snapshots of old packages from a daily archive repository.
The only publicly available snapshot archive is currently located at https://snapshot.debian.org
By default, debsnap will download all the available versions for package that are found in the snapshot archive. If a version is specified, only that particular version will be downloaded, if available.
The following options are available:
- -d destination, --destdir destination
- Directory to place retrieved packages.
- -f, --force
- Force writing into an existing destination. By default debsnap will insist the destination directory does not exist yet unless it is explicitly specified to be '.' (the current working directory). This is to avoid files being accidentally overwritten by what is fetched from the archive and to provide a guarantee for other scripts that only the files fetched will be present there upon completion.
- -v, --verbose
- Report on the debsnap configuration being used and progress during the download operation. Please always use this option when reporting bugs.
- -l, --list
- Don't download but just list versions.
- Download binary packages instead of source packages.
- -a, --architecture
- Specify architecture of downloaded binary packages. Implies --binary. This can be given multiple times in order to download binary packages for multiple architectures.
- Specify the minimum version of a package which will be downloaded. Any versions which compare larger than this, according to dpkg, will be considered for download. May be used in combination with --last.
- Specify the maximum version of a package which will be downloaded. Any package versions which compare less than this, according to dpkg, will be considered for download. May be used in combination with --first.
- -h, --help
- Show a summary of these options.
- Show the version of debsnap.
debsnap may also be configured through the use of the following options in the devscripts configuration files:
- Same as the command line option --verbose. Set to yes to enable.
- Set a default path for the destination directory. If unset ./source-<package_name> will be used. The command line option --destdir will override this.
- The base url for the snapshots archive.
If unset this defaults to https://snapshot.debian.org
debsnap will return an exit status of 0 if all operations succeeded, 1 if a fatal error occurred, and 2 if some packages failed to be downloaded but operations otherwise succeeded as expected. In some cases packages may fail to be downloaded because they are no longer available on the snapshot mirror, so any caller should expect this may occur in normal use.
