You heard that right folks no more do you have to deal with the frequent (yet some times annoying) updates and security patches to the kernel, that invokes downtime in most cases. Now you can apply those security patches without any intervention from you and that too without a system restart! And better yet, it’s free for use on up to 3 machines! 😱
What Am I talking about, you ask!?
I am talking about Ubuntu's new LivePatch Service. If you are interested in setting this up follow simple steps stated below and you'll be good to go!
1. Create an Ubuntu One Account
If you don't already have an Ubuntu One account head on over to their portal here and create a new account.
2. Install Snapd
**Snapd** is a REST API daemon for managing snap packages. Users can interact with it by using the snap client, which is part of the same package. You can package any app for every Linux desktop, server, cloud or device.
sudo apt update && sudo apt install snapd
At this point, if you are running an Ubuntu 14.04 LTS, you are required to run the Ubuntu v4.4 kernel in Trusty. Please reboot into the correct kernel if you are not currently running it.
3. Install canonical-livepatch
Install canonical livepatch using the following command on your terminal
sudo snap install canonical-livepatch
4. Enable canonical-livepatch
Now you can head over to Ubuntu's livepatch page and retrieve your own token. Ex:
d3b07384d213edec49eaa6238ad5ff00. Then you can enable
canonical-livepatch using the token obtained earlier, on your server/machine, using the following command:
sudo canonical-livepatch enable d3b07384d113edec49eaa6238ad5ff00
5. And You are all set!
That's all you need now you can check your status at anytime using the below command:
canonical-livepatch statuskernel: 4.4.0-70.91~14.04.1-genericfully-patched: trueversion: "21.1"
That's All Folks! 🐰🥕
