Ubuntu updates say that I can use Livepatch


#1

Hello all, when I get updates for my Ubuntu 18.04 I get a reminder that I can use Livepatch to keep my laptop secure between restarts ? How can I do this? I don’t find it in the Ubuntu software. Thank you for any info on this. Ray

Hi Ray, the best person to answer this will @abhishek in the meanwhile I found this https://www.ubuntu.com/livepatch I don’t know if it will help with anything or not as I don’t use Ubuntu so couldn’t really say

Thank you ElectricDandySlider, I’ll look into it.

Live patching is essentially a server thing where restarts matter a lot. What it means is that when there are kernel updates from Ubuntu, you won’t need to restart your system in order to apply those patches.

You might have noticed that Ubuntu prompts you to restart your system after updates, sometimes. On desktop it’s not an issue because you probably shutdown your system often. But on servers, a system restart could result in website/app/service downtime. This is why live patching is used.

Ubuntu has recently enabled this feature for desktop system as well. Though I don’t think it’s a critical feature but if you want to use it, you can find it in Software & Updates:

You’ll need to create an Ubuntu ID in order to use this feature: https://login.ubuntu.com/+login

Thanks for the explanation Abhishek, Guess I don’t need it. Ray

Checked ‘Updates’ tab and it’s not an available option in Xubuntu 18.10. So is it only “Ubuntu vanilla” that has it or some other flavours too ??
