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 is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
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.
