First time using Ubuntu Pro

Hola,

So, I read a news about "Ubuntu Pro is Now Available to Anyone Who Wants It" and the banner always said it every time I logged in to my SSH session.

Welcome to Ubuntu 20.04.5 LTS (GNU/Linux 5.4.0-28-generic x86_64)

 * Documentation:  https://help.ubuntu.com
 * Management:     https://landscape.canonical.com
 * Support:        https://ubuntu.com/advantage

 * Introducing Expanded Security Maintenance for Applications.
   Receive updates to over 25,000 software packages with your
   Ubuntu Pro subscription. Free for personal use.

Quoted from OMGUbuntu:

Canonical say tens of thousands of Ubuntu users signed up for the service while it was in beta, and that it is already in production “for large-scale customers offering global services”.

As part of Ubuntu Pro, Canonical manage critical, high, and selected medium CVEs for “thousands of applications and toolchains” including Ansible, Apache Tomcat, Docker, Nagios, Node.js, phpMyAdmin, Puppet, Python, Redis, Rust, WordPress, and more — all while remaining compliant with regimes like FedRAMP, HIPAA, and PCI-DSS.

Ubuntu Pro also includes Livepatch. Livepatch allows critical and high-severity kernel vulnerabilities to be patched “live”, without the need to reboot.

Ubuntu Pro is free for personal use on up to 5 PCs. Ubuntu members can use it for free on up to 50 PCs. For business, a standard Ubuntu Pro subscription costs $25/year for workstation or $500/year for server. A 30-day free trial is available.

This chart provides a quick and easy overview of the support:

So, I take this chance to attach Ubuntu Pro to my idle Ubuntu VPS on GreenCloud

First, log in to Ubuntu.com and then navigate Ubuntu Pro Dashboard

To enable Ubuntu Pro, I attached my machine with

sudo pro attach yourtoken

Output:

And after a few days of not logged-in to my VPS, seems like my Ubuntu VPS updated automatically with Canonical Livepatch service. It's notified on motd.

*** Livepatch has fixed kernel vulnerabilities. System restart recommended on the closest maintenance window ***

Because I worked in the Web Hosting industry, maybe it's similar to KernelCare from CloudLinux.

That's it maybe for now.

Thank you for reading, take care!
