*Upgrade and Reboot Interval: Security patches are only created for a kernel for 9-13 months from the release date of the kernel. We recommend updating and restarting your machine within this period to continue receiving Livepatch updates.

GA is the kernel a release launched with, while HWE or Hardware Enablement kernels are a set of newer kernel that become available in the current LTS release as these newer kernels are released with subsequent Ubuntu versions, up until the next LTS release.

There will be Livepatch support for HWE kernels across a limited combination of kernel flavour (variants), kernel version, and Ubuntu release as detailed above.

See this page to better understand why your kernel might not be supported.

Hi! Per the kernel release cycle, 6.2 is EOL as of January 2024. Can it be removed from this page?

This has now been done. Future automation should make this more automatic, thanks.

Is anyone else having 502 Bad Gateway issues when trying to enable or attach livepatch for Ubuntu 22.04 LTS?

@rebroad1 We are looking into this and it seems like a temporary issue. Could you please try again later?

I am experiencing something similar with Livepatch.
This is the status I am getting:

$ sudo canonical-livepatch status
last check: 5 minutes ago
kernel: 6.8.0-52.53-generic
server check-in: failed: livepatch check failed: error response with status 503 (Service Unavailable): “<h 1>503 Service Unavailable</h 1>\ nNo server is available to handle this request.\ n\ n\ n”
kernel state: ✓ kernel series 6.8 is covered by Livepatch
patch state: ✓ no livepatches available for kernel 6.8.0-52.53-generic
tier: updates (Free usage; This machine beta tests new patches.)

Just so no one keeps saying “me, too” or asking about the state of the Livepatch service (or any other service Canonical provides), I’ll point out that https://status.canonical.com/ is a useful tool for finding out if there are any service issues.

You can see Livepatch is mentioned there right now:

@rebroad1 @couroderato Livepatch server is back up and your clients should report everything is fine. However, if there are still issues you can try disabling and enabling Livepatch through the Ubuntu Pro client:

sudo pro disable livepatch
sudo pro enable livepatch

Please let me know if you are still seeing status errors.

Everything is working fine. Thank you!

Also, sorry for unnecessarily adding my case without checking the servers status webpage first. I did tried to search for something of that sort, but I seems I could find everything else but what I needed.
