Livepatch - Does This Even Do Anything?

So, I installed LivePatch on 2 machines. One of them Ubuntu 20.04.2 and the other 18.04.5. New kernel versions came with security fixes. LivePatch did not do anything. I had to install the new kernel updates and still reboot. What am I missing here? Does LivePatch even do anything? I don't think so...

Solution 1:

Check your kernel versions. Livepatch supports only GA kernels (the ones that are the official ones at the LTS release). If you manually update the kernel, you may end in a different (newer) version that is not supported.

Check versions here: https://ubuntu.com/security/livepatch/docs/kernels
