[CLOSED] Kernel livepatch with canonical-livepatch tool

Hi, Can I use Canonical Livepatch on my Arch Linux Desktop?

I have look around and I can't see a detailed list about which OS are really supported.

I have found that only debian-based have installed this using Snap from the *Users by distribution* section on https://snapcraft.io/canonical-livepatch.

Thanks!

At minimum you need to install and run a kernel that is supported by livepatch.

Oh, I didn't notice that. The livepatch has to be adapted to every kernel release?
The Ubuntu 18.10 comes with kernel v4.18, but livepatch will not work properly on kernel 4.19?

Not only that, I think you need to run the exact kernel as compiled by canonical. Only then will the patch files match.

I'm not sure about that, because in the snapcraft link you can see OS like Debian, Mint, KDE Neon, ElementaryOS as distros where this was installed. I'm not sure if all of these use canonical kernels packages, but Debian is the Ubuntu father and if this works on Debian that should not be a problem.

Please do contact Canonical to verify this.
