Livepatch -- plans to support official HWE kernels?

  • 772

According to an answer to this question, livepatch supports only the release kernels for a given LTS release. This is understandable, in order to make development and support a possible task, but I've installed HWE on the last two versions on my daily driver (16.04 and 20.04) in order to obtain support for math libraries required for a Kerbal Space Program mod (Kopernicus, the real-gravity multi-body add-on).

I'd love to be able to keep my kernel updated without reboots that require reopening software I leave running in the background, and in general just to see the uptime line in my Conky get bigger than about 20 days.

Are there any known plans for livepatch to support these (from Canonical) HWE kernels?

    If you have an Ubuntu One account, you can do Livepatch for HWE Kernels for personal use on up to 3 systems. You will need to get a token for it to work.

    Visit https://auth.livepatch.canonical.com/ to get your token.

    Once you have your token you should be able to activate Livepatch on your system using the ua tool.

    sudo ua enable-livepatch <token>

    Then Livepatch should be working for HWE Kernels.
