Ubuntu Advantage Client

The Ubuntu Advantage (UA) client is a tool designed to automate access to UA services like Extended Security Maintenance (ESM), CIS, FIPS, and more. The client is available for all Ubuntu LTS releases. Features might depend on the specific LTS release as they do or do not apply. The updated client provides users a command-line interface with a single point to access all UA services. This simplifies access to UA Services and allows access to UA services for all users of Ubuntu with a free tier of service. See https://ubuntu.com/advantage for more details on the various UA services.

Working with specific services

Extended Security Maintenance (ESM)

  1. Make sure that you have the latest UA client installed on your Ubuntu 16.04 LTS machine.
  2. Follow the instructions on https://ubuntu.com/advantage/ to retrieve your UA token and get started with ESM.

Keep reading if you want more detailed instructions, or have questions

Installing the UA client

The UA client is installed through apt. Make sure to confirm you have the latest Ubuntu Advantage client which is equal to or greater than version 27.

$ ua --version

Once you have verified your client, you will need to attach it to your UA account.

Attach the UA client

Retrieve your UA token from https://ubuntu.com/advantage/. You will log in with your SSO credentials, the same credentials you use for https://login.ubuntu.com.

$ sudo ua attach YOUR_TOKEN

You should see output like the following, indicating that you have successfully associated this machine with your account.

Extended Security Maintenance (ESM)

For Ubuntu 14.04 LTS and 16.04 LTS as shown above, ESM will be automatically enabled after attaching the UA client to your account. After ubuntu-advantage-tools is installed and your machine is attached, ESM should be enabled. If ESM is not enabled, you can enable it with the following command:

$ sudo ua enable esm-infra

With the ESM repository enabled, you may see a number of additional package updates available that were not available previously. Your system may have indicated that it was up to date before installing the ubuntu-advantage-tools, but make sure to check for new updates with apt update. If you have cron jobs set to install updates, or other unattended upgrades configured, be aware that this will likely result in a number of package updates after ESM is enabled.

$ sudo apt update

Running apt upgrade will show a number of package updates available.

$ sudo apt upgrade

More information: https://ubuntu.com/security/esm

Livepatch

Livepatch requires:

To enable run:

$ sudo ua enable livepatch

You should see output like the following, indicating that the Livepatch snap package has been installed.

One moment, checking your subscription first
Installing snapd
Updating package lists
Installing canonical-livepatch snap
Canonical livepatch enabled.

To check the status of Livepatch once it has been installed use this command

$ sudo canonical-livepatch status

More information: https://ubuntu.com/security/livepatch

CIS Audit Tools

To access the CIS tooling first enable the software repository.

$ sudo ua enable cis
Installing CIS Audit packages
CIS Audit enabled
Visit https://security-certs.docs.ubuntu.com/en/cis to learn how to use CIS

Once the feature is enabled please follow the documentation for the CIS tooling to run the provided hardening audit scripts.

Security Certifications (FIPS / Common Criteria)

FIPS and Common Criteria are supported on 16.04+, please see https://docs.ubuntu.com/security-certs/en/. The UA client will be updated for 16.04+ at a later date.

Proxy Configuration

Note (2021-07-07): Proxy configuration is currently only available in the UA Client Daily PPA, but will be released as a standard Ubuntu update v27.2 in the coming weeks.

The UA Client can be configured to use an http/https proxy as needed for network requests. In addition, the UA Client will automatically set up proxies for all programs required for enabling Ubuntu Advantage services. This includes APT, Snaps, and Livepatch.

HTTP/HTTPS Proxies

To configure standard http and/or https proxies, run the following commands:

$ sudo ua config set http_proxy=http://host:port
$ sudo ua config set https_proxy=https://host:port

After running the above commands, UA Client performs the following:

  1. Verifies that the proxy is working by using it to reach api.snapcraft.io
  2. Configures itself to use the given proxy for all future network requests
  3. If snapd is installed, configures snapd to use the given proxy
  4. If Livepatch has already been enabled, configures Livepatch to use the given proxy
    1. If Livepatch is enabled after this command, UA Client will configure Livepatch to use the given proxy at that time.

To remove http/https proxy configuration, run the following:

$ sudo ua config unset http_proxy
$ sudo ua config unset https_proxy

After running the above commands, UA Client will also remove proxy configuration from snapd (if installed) and Livepatch (if enabled).

APT Proxies

APT proxy settings are configured separately. To have UA Client manage your APT proxy configuration, run the following commands:

$ sudo ua config set apt_http_proxy=http://host:port
$ sudo ua config set apt_https_proxy=https://host:port

After running the above commands, UA Client:

  1. Verifies that the proxy works by using it to reach archive.ubuntu.com or esm.ubuntu.com.
  2. Configures APT to use the given proxy by writing an apt configuration file to /etc/apt/apt.conf.d/90ubuntu-advantage-aptproxy.

Note: Any configuration file that comes later in the apt.conf.d directory could override the proxy configured by the UA Client.

To remove the APT proxy configuration, run the following:

$ sudo ua config unset apt_http_proxy
$ sudo ua config unset apt_https_proxy

Authenticating

If your proxy server requires authentication, you can pass the credentials directly in the URL when setting the configuration, as in:

$ sudo ua config set https_proxy=https://username:password@host:port

Checking the configuration

To see what proxies UA Client is currently configured to use, you can use the show command.

$ sudo ua config show

The above will output something that looks like the following if there are proxies set:

http_proxy      http://proxy
https_proxy     https://proxy
apt_http_proxy  http://aptproxy
apt_https_proxy https://aptproxy

Or it may look like this if there aren’t any proxies set:

http_proxy      None
https_proxy     None
apt_http_proxy  None
apt_https_proxy None

FAQ

General

Why are we updating the client?

The updated client provides users a command-line interface with a single point to access all UA services. This reduces the number of tokens a customer has to manage as the old mechanism was one token per service.

Will the old ESM system stay in place for the entire Ubuntu 14.04 LTS ESM lifetime?

Yes. If you have ESM provisioned using the old client or manually you do not have to change.

Ubuntu.com/advantage shows I have 0? Why? I have more licenses.

The number is showing 0 attached to the subscription - not your total license amount.

Attach

How do I attach/login/activate?

You have to obtain your token and run: ua attach <token>

Where do I get a token?

How do I use SSO?

SSO is available from a user’s Ubuntu One account and can be created at https://login.ubuntu.com/.

What services get enabled by default?

ESM would be enabled by default where possible. Livepatch will not be auto-enabled on Ubuntu 14.04 LTS, but is enabled by default on later series. If a service is not applicable on the platform or release then the service will be skipped

I already have UA, and use Landscape to manage my devices, can I attach and manage UA from Landscape?

Not at this time. That said, you can automate the rollout using Landscape’s ability to execute commands on systems under management.

Status

What does ‘’‘entitled’’’ mean?

Entitled shows whether your contract with us includes this Ubuntu Advantage service or not.

Why does the STATUS column say ‘’‘n/a’’’ if I am ‘’‘entitled’’’ to the service?

This service may not be applicable to the system you are currently on. Here are some examples:

  • FIPS is currently only supported on Xenial and Bionic. If you are on any other release, FIPS would show up as ‘’‘n/a’’’.
  • On Ubuntu 14.04 LTS, Livepatch is only available if you have the HWE kernel installed and are booted into it. Otherwise it shows ‘’‘n/a’’’.
  • If you are on a container, you cannot install Livepatch.

Issues/Bugs/Debug

Where can I file bugs?

Things are failing, what logs are useful?

First, consider using the --debug option to see what might be failing. Otherwise, checkout /var/log/ubuntu-advantage.log. If including this log file in a bug report, please sanitize it first, as it will likely contain secrets!

I’m attaching successfully, but not showing entitled to anything? I have a commercial contract.

Please open a https://support.canonical.com/ with the output of sudo ua status --format json

I upgraded from Trusty with ESM to Xenial and now it does not show I have ESM enabled any longer
This is a known issue and can be resolved by re-enabling ESM using sudo ua enable esm-infra after rebooting the system into Xenial. See https://github.com/canonical/ubuntu-advantage-client/issues/1590

My cloud-init cloud-config is no longer working to enable UA products
Customers using the following cloud-config userdata will have to update to use the new cmdline client ‘ua attach’, ‘ua enable’ commands.

   #cloud-config
     ubuntu_advantage:
         commands: XXX
     runcmd:
         ubuntu-advantage enable-fips

I find customers also like to know that running <canonical-livepatch status --format yaml> and <canonical-livepatch status --verbose> will tell you which livepatch is currently enabled and which CVEs it’s protecting you from (otherwise some people can end up updating and rebooting every time their sys mgmt tool alerts them to a vulnerability)

I would repeat this question for Livepatch, especially because at some point we will recommend that users move from the Livepatch-specific token to the UA client.

Can we please tweak this to be more applicable to Pro users on the clouds? Specifically I am thinking, for example, of a statement upfront that, if you are running Ubuntu Pro on Azure/AWS/GCE, you should already have a recent version of the ua-client installed and it should already be attached, so you can likely go straight to the sudo ua status step.

We could also add a reference to Ubuntu Pro in the “Where do I get a token?” FAQ. Something along the lines that “Our recommended approach to obtain services like Livepatch and ESM on the Public Clouds is to use Ubuntu Pro. For other use cases you can purchase Ubuntu Advantage directly from Canonical: [existing link].”

I am not sure about having this part at the beginning:

I think you have done a great job summarising the value of ua client and how to install and configure it. I wonder if specific guidance on enabling ESM to 14.04 or 16.04 belongs somewhere else separately (e.g. on our 16.04 page). That would also give us greater flexibility to tailor the advice to, for example, Public Cloud users, who in some cases have better options.

Should we add in a ua version so that people who do have the latest version aren’t adding a ppa etc? I wonder if we should just tell people to run ua version and check it is at least 26.3 (and follow your steps if not) – if they have a version >= 26.3 do they need the very latest from a ppa?

I can appreciate the nice to know information but I’d leave those details to the livepatch documentation vs this specific to enabling UA services. We do reference them to the livepatch content for more information.

We’ll see if we get more questions/feedback there and balance how much detail about each service best serves users here.

I just purchased an Ubuntu Advantage package t get ESM for 16.04 LTS.

My server has unattended-upgrades and my /etc/apt/apt.conf.d/50unattended-upgrades file currently looks like this:

Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        // Extended Security Maintenance; doesn't necessarily exist for
        // every release and this system may not have it installed, but if
        // available, the policy for updates is such that unattended-upgrades
        // should also install from here by default.
        "${distro_id}ESM:${distro_codename}";
//      "${distro_id}:${distro_codename}-updates";
//      "${distro_id}:${distro_codename}-proposed";
//      "${distro_id}:${distro_codename}-backports";
};

I am confused about what should actually be present in there to only get security updates including the ESM updates, because I have also seen these lines (which are different from what seems to be present in my configuration):

"${distro_id}ESMApps:${distro_codename}-apps-security";
"${distro_id}ESM:${distro_codename}-infra-security";

So: to enable ESM security updates for 16.04 LTS, which line(s) should I actually add in my 50unattended-upgrades file?

I’m now also wondering if that very first line ( “${distro_id}:${distro_codename}”, so without the “-security” suffix) is actually needed…

Thanks for any clarifications!

The key line I’d expect for 16.04 esm is the one for the -infra-security like:

"${distro_id}ESM:${distro_codename}-infra-security";

That said, if there are system issues so bad, or issues that prevent a system from enabling ESM there could be required updates in the original repositories

    "${distro_id}:${distro_codename}";
    "${distro_id}:${distro_codename}-security";

So I’d suggest having those three enabled.

Thanks so much for your fast reply!
All sounds reasonable, so I will do as you suggest.

Do you have any idea, why my configuration line would look like this instead of the suggested one:

Is there a place where I can read up on what these various origins (ESM-related or otherwise) mean/imply?
