canonical-livepatch-downloader

canonical-livepatch-downloader is a command-line application for querying and downloading Canonical Livepatch patch files. It is designed for Linux users who need basic patch retrieval functions in situations where the Canonical Livepatch client is not supported. The tool does not replace the Canonical Livepatch client and instead provides a narrower set of download and query operations.

Users enable the tool with the enable command and an Ubuntu Pro token obtained from the Ubuntu Pro dashboard. The token must be entitled to Livepatch and must belong to the stable tier. The get-latest command retrieves the latest patch for a system, with options required for the target architecture and kernel. The command-line help provides more information about those required flags.

The list command shows available patches and can filter results by kernel or architecture. Users can use its output with get-files to download a selected list of files. The -K or --keep-tarball option also saves the downloaded patch tarball. Downloaded patches are stored under ~/snap/canonical-livepatch-downloader/common/patches, while retained tarballs are stored under ~/snap/canonical-livepatch-downloader/common/tarballs.

The product is listed for the Linux platform in the Security & Privacy category and is distributed under a commercial license. MirrorNest links directly to the official release rather than hosting a mirrored copy. This distribution model lets users access the release through the catalog while obtaining the software from its official source. Removing the downloader can create a snapshot that may be large after several patches have been downloaded, and the documented purge command avoids creating that snapshot.
