API reference guide:
https://canonical-ubuntu-pro-client.readthedocs-hosted.com/en/latest/references/api/
attach [-h] [--no-auto-enable] [--attach-config ATTACH_CONFIG] [--format {cli,json}] [token]
Attach this machine to an Ubuntu Pro subscription with a token obtained from:
https://ubuntu.com/pro/dashboard
When running this command without a token, it will generate a short code and prompt you to attach
the machine to your Ubuntu Pro account using a web browser.
The "attach-config" option can be used to provide a file with the token and optionally, a list of
services to enable after attaching. To know more, visit: https://canonical-ubuntu-pro-
client.readthedocs-hosted.com/en/latest/howtoguides/how_to_attach_with_config_file/
The exit code will be:
* 0: on successful attach
* 1: in case of any error while trying to attach
* 2: if the machine is already attached
auto-attach [-h]
Automatically attach on an Ubuntu Pro cloud instance.
collect-logs [-h] [-o OUTPUT]
Collect logs and relevant system information into a tarball. This information can be later used
for triaging/debugging issues.
cve [-h] cve
Show all available information about a given CVE.
cves [-h] [--unfixable] [--fixable]
List the CVE vulnerabilities that affects the system.
config [-h] {show,set,unset} ...

fix [-h] [--dry-run] [--no-related] security_issue
Inspect and resolve Common Vulnerabilities and Exposures (CVEs) and Ubuntu Security Notices (USNs)
on this machine.
The exit code will be:
* 0: the fix was successfully applied or the system is not affected
* 1: the fix cannot be applied
* 2: the fix was applied but requires a reboot before it takes effect
help [-h] [--format {tabular,json,yaml}] [--all] [service]
Provide detailed information about Ubuntu Pro services.
refresh [-h] [{contract,config,messages}]
Refresh three distinct Ubuntu Pro related artifacts in the system:
* contract: Update contract details from the server.
* config: Reload the config file.
* messages: Update APT and MOTD messages related to Pro.
You can individually target any of the three specific actions, by passing the target name to the
command. If no target is specified, all targets are refreshed.
security-status [-h] [--format {json,yaml,text}] [--thirdparty | --unavailable | --esm-infra | --esm-
apps]
Show security updates for packages in the system, including all available Expanded Security
Maintenance (ESM) related content.
Shows counts of how many packages are supported for security updates in the system.
If the format is set to JSON or YAML it shows a summary of the installed packages based on the
origin:
- main/restricted/universe/multiverse: Packages from the Ubuntu archive.
- esm-infra/esm-apps: Packages from the ESM archive.
- third-party: Packages installed from non-Ubuntu sources.
- unknown: Packages which don't have an installation source (like local
deb packages or packages for which the source was removed).
The output contains basic information about Ubuntu Pro. For a complete status on Ubuntu Pro
services, run 'pro status'.
status [-h] [--wait] [--format {tabular,json,yaml}] [--simulate-with-token TOKEN] [--all]
Report current status of Ubuntu Pro services on system.
This shows whether this machine is attached to an Ubuntu Pro support contract. When attached, the
report includes the specific support contract details including contract name, expiry dates, and
the status of each service on this system.
The attached status output has four columns:
* SERVICE: Name of the service.
* ENTITLED: Whether the contract to which this machine is attached
entitles use of this service. Possible values are: yes or no.
* STATUS: Whether the service is enabled on this machine. Possible
values are: enabled, disabled, n/a (if your contract entitles
you to the service, but it isn't available for this machine) or - (if
you aren't entitled to this service).
* DESCRIPTION: A brief description of the service.
The unattached status output instead has three columns. SERVICE and DESCRIPTION are the same as
above, and there is the addition of:
* AVAILABLE: Whether this service would be available if this machine
were attached. The possible values are yes or no.
If "simulate-with-token" is used, then the output has five columns. SERVICE, AVAILABLE, ENTITLED
and DESCRIPTION are the same as mentioned above, and AUTO_ENABLED shows whether the service is set
to be enabled when that token is attached.
If the "all" flag is set, beta and unavailable services are also listed in the output.
system [-h] {reboot-required} ...
Output system-related information about Pro services.
reboot-required [-h]
Report the current reboot-required status for the machine.
This command will output one of the three following states for the machine regarding reboot:
* no: The machine doesn't require a reboot.
* yes: The machine requires a reboot.
* yes-kernel-livepatches-applied: There are only kernel-related
packages that require a reboot, but Livepatch has already provided
patches for the current running kernel. The machine still needs a
reboot, but you can assess if the reboot can be performed in the
nearest maintenance window.
SERVICES
Anbox Cloud (anbox-cloud)
Anbox Cloud lets you stream mobile apps securely, at any scale, to any device, letting you focus
on your apps. Run Android in system containers on public or private clouds with ultra low
streaming latency. When the anbox-cloud service is enabled, by default, the Appliance variant is
enabled. Enabling this service allows orchestration to provision a PPA with the Anbox Cloud
resources. This step also configures the Anbox Management Service (AMS) with the necessary image
server credentials.
To learn more about Anbox Cloud, see https://anbox-cloud.io
Common Criteria EAL2 Provisioning (cc-eal)
Common Criteria is an Information Technology Security Evaluation standard (ISO/IEC IS 15408) for
computer security certification. Ubuntu 16.04 has been evaluated to assurance level EAL2 through
CSEC. The evaluation was performed on Intel x86_64, IBM Power8 and IBM Z hardware platforms.
CIS Audit (cis)/Ubuntu Security Guide (usg)
Ubuntu Security Guide is a tool for hardening and auditing, allowing for environment-specific
customizations. It enables compliance with profiles such as DISA-STIG and the CIS benchmarks.

Expanded Security Maintenance for Infrastructure (esm-infra)
Expanded Security Maintenance for Infrastructure provides access to a private PPA which includes
available high and critical CVE fixes for Ubuntu LTS packages in the Ubuntu Main repository
between the end of the standard Ubuntu LTS security maintenance and its end of life. It is enabled
by default with Ubuntu Pro.
You can find out more about the service at https://ubuntu.com/security/esm
Expanded Security Maintenance for Applications (esm-apps)
Expanded Security Maintenance for Applications is enabled by default on entitled workloads. It
provides access to a private PPA which includes available high and critical CVE fixes for Ubuntu
LTS packages in the Ubuntu Main and Ubuntu Universe repositories from the Ubuntu LTS release date
until its end of life.
You can find out more about the esm service at https://ubuntu.com/security/esm
FIPS 140-2 certified modules (fips)
Installs FIPS 140 crypto packages for FedRAMP, FISMA and compliance use cases. Note that "fips"
does not provide security patching. For FIPS certified modules with security patches please see
"fips-updates". If you are unsure, choose "fips-updates" for maximum security.
Find out more at https://ubuntu.com/security/fips
FIPS 140-2 certified modules with updates (fips-updates)

/etc/apt/apt.conf.d/90ubuntu-advantage-aptproxy. Set this if you prefer a global proxy for all
resources, not just the ones from esm.ubuntu.com
global_apt_https_proxy
If set, pro will configure apt to use the specified https proxy by writing a apt config file to
/etc/apt/apt.conf.d/90ubuntu-advantage-aptproxy. Set this if you prefer a global proxy for all
resources, not just the ones from esm.ubuntu.com
ua_apt_http_proxy
If set, pro will configure apt to use the specified http proxy by writing a apt config file to
/etc/apt/apt.conf.d/90ubuntu-advantage-aptproxy. This proxy is limited to accessing resources from
esm.ubuntu.com
ua_apt_https_proxy
If set, pro will configure apt to use the specified https proxy by writing a apt config file to
/etc/apt/apt.conf.d/90ubuntu-advantage-aptproxy. This proxy is limited to accessing resources from

<job_name>_timer
Sets the timer running interval for a specific job. Those intervals are checked every time the
systemd timer runs.
apt_news
If set to false, the Pro client will no longer display apt news messages on the output of apt
upgrade.
apt_news_url
Sets the url where the Pro client will consume apt news information from.
If needed, authentication to the proxy server can be performed by setting username and password in the
URL itself, as in:
http_proxy: http://<username>:<password>@<fqdn>:<port>
PRO UPGRADE DAEMON
Ubuntu Pro client sets up a daemon on supported platforms (currently on Azure and GCP) to detect if an
Ubuntu Pro license is purchased for the machine. If an Ubuntu Pro license is detected, then the machine
is automatically attached. If you are uninterested in Ubuntu Pro services, you can safely stop and
disable the daemon using systemctl:
sudo systemctl stop ubuntu-advantage.service sudo systemctl disable ubuntu-advantage.service
TIMER JOBS
Ubuntu Pro client sets up a systemd timer to run jobs that need to be executed recurrently. The timer
itself ticks every 5 minutes on average, and decides which jobs need to be executed based on their
intervals.
Jobs are executed by the timer script if the script has not yet run successfully, or their interval since
last successful run is already exceeded. There is a random delay applied to the timer, to desynchronize
job execution time on machines spinned at the same time, avoiding multiple synchronized calls to the same
service.
Current jobs being checked and executed are:
update_messaging
Makes sure that the MOTD and APT messages match the available/enabled services on the system,
showing information about available packages or security updates.
metering
If attached, this job will ping the Canonical servers telling which services are enabled on the
machine.
