How to Register Ubuntu Pro for Free: 10 Years of Security, Kernel Updates Without Rebooting – ITFROMZERO

Ubuntu Pro: Why Should Personal Servers Also “Upgrade”?

Many Linux beginners think that installing Ubuntu LTS means they can “sleep soundly” for 5 years. In reality, it’s not that simple. After 5 years, official security patches stop. More concerningly, thousands of packages in the universe repository—like Redis, Node.js, or Python—are often left exposed if you only use the standard Ubuntu version.

Ubuntu Pro is the “lifeline” for this issue. Previously, this service was expensive and only for enterprises. Now, Canonical has made a bold move by allowing individual users to use it for free on up to 5 machines. I have tested this configuration on a server cluster running Ubuntu 22.04. The results were impressive: the system is stable, and kernel patches are applied immediately without a single second of downtime.

Here are 3 reasons why you should enable Ubuntu Pro right now:

ESM (Extended Security Maintenance): Maintains security patches for up to 10 years, instead of the default 5 years.
Livepatch: Patches Kernel vulnerabilities while the machine is running. You no longer need to wait until 2 AM to reboot your server.
Universe Repository Security: Protects over 23,000 open-source packages outside of the Ubuntu core system.

Steps to Register an Account and Get a Token

First, you need an Ubuntu One account. Registration takes only about 2 minutes and is completely free.

Visit the home page at ubuntu.com/pro.
Register or log in to your personal account.
In the Your subscriptions section, you will see a long string of characters called a Token. Copy this code to prepare for “enchanting” your server.

Now, open the terminal window on your server. A small tip: always update the license management tools to the latest version before proceeding to avoid minor errors.

sudo apt update && sudo apt upgrade -y
sudo apt install ubuntu-advantage-tools -y

Real-world Configuration: Activating Security Shields

To turn a regular Ubuntu server into the Pro version, you only need a single command. Replace YOUR_TOKEN_HERE with the code you just obtained:

sudo pro attach YOUR_TOKEN_HERE

Once the command finishes running, the terminal will list the ready services. Usually, esm-apps and esm-infra are enabled automatically. However, the most “valuable” feature, Livepatch, sometimes needs manual activation.

1. Activate Livepatch to Skip the Reboot Step

Livepatch helps you avoid having to schedule maintenance and explain it to users every time the Kernel is updated. To enable this feature, type:

sudo pro enable livepatch

The system will automatically install the canonical-livepatch daemon. From now on, whenever there is a critical Kernel vulnerability (such as remote code execution bugs), the server will automatically load the patch directly into RAM without interrupting your applications.

2. Protect the Application Repository with ESM-Apps

By default, Ubuntu LTS only guarantees security for the main repository. If you are running Docker, Nginx, or Python libraries from the standard repository, you need ESM-Apps to ensure they are not exploited by hackers through old vulnerabilities.

sudo pro enable esm-apps

3. Trace and Fix Vulnerabilities with Pro Fix

A feature I really love is the ability to check for specific CVE errors. For example, if you hear about a new security vulnerability making headlines, you can immediately check if your server is affected:

pro fix CVE-2023-XXXXX

This command not only reports the status but also guides you on how to patch the bug in no time.

Verifying the Results

After you’re done, don’t rush to exit the terminal. Run the following command to make sure everything is running smoothly:

pro status

Watch the STATUS column; everything should display enabled. To check the details of the loaded Kernel patches, use this additional command:

canonical-livepatch status

If you see the line kernel: ... server check-in: succeeded, you can now sleep soundly.

Final Word for Administrators

If you manage about 4-5 VPS instances, typing commands manually can be quite tiring. I usually include the attach command in my initial setup script or use Ansible for full automation. Getting access to a 10-year security system for free is a great deal for those setting up labs or running personal projects. Don’t wait until your server is attacked to scramble to fix bugs. Security is a proactive process, and Ubuntu Pro is an extremely effective first line of defense that you shouldn’t overlook.
