The Canonical livepatch downloader tool is a CLI application that provides basic commands to query and download patch files.
Please note that this tool is not a replacement for the Canonical Livepatch client - https://snapcraft.io/canonical-livepatch. Instead it provides some basic patch download and query functionality for scenarios where the Canonical Livepatch client is not supported.
How To Use:
canonical-livepatch-downloader enable <token> with an Ubuntu Pro token obtained from https://ubuntu.com/pro/dashboard, note that the token must be entitled to Livepatch.canonical-livepatch-downloader get-latest. This command requires some flags, including the architecture and the desired kernel. See the help output for more info.canonical-livepatch-downloader list, which accepts filtering to your desired kernel/architecture. Use this in conjunction with canonical-livepatch-downloader get-files to download a list of files.Patches are downloaded to ~/snap/canonical-livepatch-downloader/common/patches. Removing the patch downloader will create a snapshot which may be large if you have downloaded several patches. Use sudo snap remove canonical-livepatch-downloader --purge to avoid creating a snapshot.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15.5 users, for example, can do this with the following command:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.5 snappy
Swap out openSUSE_Leap_15.5 for openSUSE_Leap_15.4 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install canonical-livepatch-downloader, simply use the following command:
sudo snap install canonical-livepatch-downloader
Browse and find snaps from the convenience of your desktop using the snap store snap.
