Get started with Ubuntu Pro

Overview

New to Ubuntu Pro? This how-to guide will help you understand how to activate your Ubuntu Pro subscription and choose which services to enable. Together, we will identify security updates that are uniquely available with an Ubuntu Pro subscription, and we will apply fixes.

We will start by getting a free, personal subscription. Then we will attach this subscription to your existing Ubuntu LTS machine.

Want to learn more about the benefits of Ubuntu Pro before moving on?

What you'll learn

1. What Ubuntu Pro is and how to use it
2. How to check the source of your installed packages
3. How to attach an Ubuntu Pro subscription to your existing Ubuntu LTS machine
4. How to check for and apply security updates on your Ubuntu machine, including security updates for Ubuntu Universe packages which are only available with Ubuntu Pro

What you'll need

1. An Ubuntu machine running 16.04 LTS, 18.04 LTS, 20.04 LTS or 22.04 LTS
2. Sudo access
3. An email address, or an existing Ubuntu One account
4. Ubuntu Pro client version 27.13.1 or newer

Before we start

1. Make sure that you are up to date:

   $ sudo apt update && sudo apt upgrade

2. Ensure that you're running the latest version of the pro client:

   $ pro --version
   27.13.1~20.04.1

I can see that I am running version 27.13.1, so no need to update. If you run a previous version of the client, you have two options:

• You could wait for the pro client update, which is now released and phased to get to all Ubuntu machines, or
• Consider bypassing the update phasing and install the latest client version using the following command:

  $ sudo apt install ubuntu-advantage-tools

• When you get the latest client, run apt update again to make sure all package data is up to date.

  $ sudo apt update

$ pro security-status
1919 packages installed:
    1870 packages from Ubuntu Main/Restricted repository
    10 packages from Ubuntu Universe/Multiverse repository
    10 package from a third party
    29 packages no longer available for download

To get more information about the packages, run
	  pro security-status --help
for a list of available options.

This machine is receiving security patching for Ubuntu Main/Restricted
repository until 2025.
This machine is NOT attached to an Ubuntu Pro subscription.

Ubuntu Pro with 'esm-infra' enabled provides security updates for
Main/Restricted packages until 2030.

Ubuntu Pro with 'esm-apps' enabled provides security updates for
Universe/Multiverse packages until 2030 and has 1 pending security update.

Try Ubuntu Pro with a free personal subscription on up to 5 machines.

OK, so there are 1919 deb packages installed on your machine.

• 1870 packages are from Ubuntu Main/ Restricted repository which means that they receive Ubuntu LTS updates until 2025. This is covered without any subscription but can be expanded with Ubuntu Pro for an additional 5 years, until 2030.
• 10 packages are from Ubuntu Universe/ Multiverse repository and they come with no security assurance from Ubuntu LTS, but they are covered by Ubuntu Pro.
• And there is 1 security update for the Universe repository available with an Ubuntu Pro subscription.

Note: if you're currently not using any packages from the Ubuntu Universe repository, that line will not be displayed.

To see the list of packages covered with esm-apps and to identify which packages have pending CVE fixes, run:

$ pro security-status --esm-apps
1919 packages installed:
	10 packages from Ubuntu Universe/Multiverse repository

Ubuntu Pro with 'esm-apps' enabled provides security updates for
Universe/Multiverse packages until 2030 and has 1 pending security update.

Run 'pro help esm-apps' to learn more

Package names in bold currently have an available update
with 'esm-apps' enabled
Packages:
ansible python3-argcomplete python3-kerberos python3-libcloud
python3-ntlm-auth python3-requests-kerberos python3-requests-ntlm
python3-selinux python3-winrm python3-xmltodict

For example, run:
	apt-cache policy ansible
to learn more about that package.

From the output we identify the list of all packages installed from the Universe repository, and we know that the CVE updated concerns ansible.

Alternatively, if you know the CVE number you want to check, the pro fix command can tell you if the machine is vulnerable or not. As an example, let's check for the CVE-2021-3583, run:

$ pro fix CVE-2021-3583
CVE-2021-3583:
A flaw was found in Ansible, where a user's controller is vulnerable to
template injection. This issue can occur through facts used in the template
if the user is trying to put templates in multi-line YAML strings and the
facts being handled do not routinely include special template characters.
This flaw allows attackers to perform command injection, which discloses
sensitive information. The highest threat from this vulnerability is to
confidentiality and integrity.
https://myasnchisdf.eu.org/security/CVE-2021-3583
1 affected source package is installed: ansible
(1/1) ansible:
A fix is available in Ubuntu Pro with `esm-apps` enabled.
The update is not installed because this system is not attached to a subscription.

To fix that we need an Ubuntu Pro subscription. Let's get one!
