Apertis 18.06 Release

18.06 is the current stable development release of Apertis, a Debian/Ubuntu derivative distribution geared towards the creation of product-specific images for ARM (both the 32bit ARMv7 and 64-bit ARMv8 versions using the hardfloat ABI) and Intel x86-64 (64-bit) systems.

This Apertis release is based on top of the Ubuntu 16.04 (Xenial) LTS release with several customizations. Test results of the 18.06 release are available in the 18.06 test report.

Release downloads

Apertis 18.06 images
Intel 64-bit Intel 64 bit Minimal Image Intel 64 bit Target Image Intel 64 bit Development Image Intel 64 bit SDK Image
ARM 32-bit (U-Boot) ARM 32 bit Minimal Image
ARM 32-bit (MX6q Sabrelite) ARM 32 bit Minimal Image
ARM 64-bit (U-Boot) ARM 64 bit Minimal Image

The Intel minimal, target and development images are tested on the reference hardware (MinnowBoard MAX), but they can run on any UEFI-based x86-64 system. The sdk image is tested under VirtualBox.

New features

Official supported images for i.MX6 Sabrelite boards

The i.MX6 Sabrelite board is now officially supported by the main image set with the new mx6qsabrelite image variant.

The headless minimal images are fully supported, while images with the full grahics stack are still in the works.

This means that anybody can deploy the publicly available mx6qsabrelite system images on i.MX6 Sabrelite and start experimenting with Apertis on their hardware.

Linux kernel v4.14 available on all the supported platforms

The 4.14 LTS version of the mainline Linux kernel is now used by every supported platform. Previously different releases were used on each platform, ranging from 3.14 to 4.4 and 4.9, all build from different source packages.

Apertis now offers support of all the supported platforms using kernels build from a single, common source packages, providing an updated and supported baseline and simplifying maintainance and development of new features.

SDK for platform development

The focus for the Apertis SDK so far has been centered on application development but from this release we started to make it more useful for platform developers that want to hack to the base Apertis system. In this release new packages for the SDK have been made available, configuration tweaks have been applied and several little nuisances have been addressed.

Code hosting on GitLab

All the Apertis code repositories have been migrated to the new GitLab instance hosted by the Apertis team.

GitLab brings Apertis many benefits over the previous setup:

  • better web UI
  • site-wide source code search
  • the availability of a merge-request based review workflow
  • finer grained access controls
  • built-in continuous automation

Phabricator is still used for task tracking and for patch review. A GitLab merge-request based review workflow to replace the latter is being defined.

The CGit code hosting service has been obsoleted and is now read-only. Redirects have been put in place to route requests from the old service to tne new one.

Closed the CI loop by automatically opening issues on automated test failures

A way to automatically file new bugs and update them when a test is failing has been designed and its implementation is being finalized.

A new service gets tests results out of LAVA, processes them and then connects to the Phabricator APIs to open new task or update existing ones.

Managers can now rely on the tasks on Phabricator to check the health of the testsuite and developers get timely updates about the latest status of failing tests.

Quality Assurance

Testcase prioritization

A priority level has been assigned to each testcase in order to better schedule their execution, to clearly identify release blockers and to prioritize maintainance and improvements.

Testcases ported to run on the OSTree images

More testcases have been ported to avoid dependencies in a way that they can be run without installing new packages on the base image.

This has two benefits:

  • makes testing more valuable by not perturbing the actual base image
  • allows those tests to be executed on OSTree images

Test ADE as part of the continuous test rounds

Tests exercising cross-building and remote debugging using the ADE (Apertis Development Environment) tool are now part of the weekly test reports.

Build and integration

Image recipes cleanups

The Apertis image recipes have seen several cleanups and improvements in order to make them simpler, faster, more robust, and easier to maintain and customize. Further improvements are planned and being worked on.

Design and documentation

All documents available in PDF format

Line-numbered PDF versions of the design documents are available for download in order to provide a better offline reading experience.

To get them, replace the .html extension in the URL with .pdf, for instance system-updates-and-rollback.html becomes system-updates-and-rollback.pdf.

Improving storage and handling of the definitions and results of testcases

A new set of concept documents has been worked on to address some shortcomings in the current infrastructure about the best way to store testcase definitions, to handle test results and to process those results to provide reliable reporting.

Improvement to the System updates and rollback document

A list of use-cases has been added to the System updates and rollback design document in order to guide the evaluation of features and approaches.

Several other improvements and clarifications have been applied to the document based on the feedback gathered.

Security aspects of OSTree

The updates and rollback design document has been updated to cover the security aspects of OSTree, describing how updates are verified and how it relates to other technologies that can be used in verified boot solutions.

Examples of key OSTree commands for Apertis images

A few OSTree commands have been collected in Docs/OSTree to provide a reference of important operations for developers:

  • updating the system
  • list locally available deployments
  • rolling back to previous releases
  • enabling temporary read-write access to the system

Deprecations and ABI/API breaks


During this release cycle we have continued to mark obsolete or problematic APIs with the ABI break tag as a way to clear technical debt in future.

Development images

The development image type is deprecated in favour of extending the target image type
From the next release Apertis will no longer ship development images, covering the use-cases addressed by them by adding the needed packages to the target image type.

Mildenhall UI framework

The Mildenhall UI toolkit is deprecated in favour of other UI toolkits such as GTK+, Qt, or HTML5-based solutions
From the next release Apertis may no longer ship the Mildenhall UI toolkit nor any accompanying libraries, as the underlying Clutter library has been deprecated upstream for some years now.

Application framework

ribchester-full and canterbury-full are deprecated
From the next release Canterbury and Ribchester will only offer the APIs provided by the respective -core and the additional APIs offered by the -full packages will be dropped


SSH addresses for Git repositories need to be manually updated
With the move to GitLab the location of the Apertis Git repositories has changed: HTTP(S) redirects have been put in place to transparently route requests, but no similar mechanism is available for SSH, so SSH remotes will need to be updated manually

xterm is no longer available on the SDK images, replaced by xfce4-terminal
The lack of support for "modern" features like supports copy-and-paste in xterm<code> confused some users and it has been replaced by <code>xfce4-terminal


Apertis infrastructure tools

The Apertis Debian Stretch tools repositoriy provides packages for git-phab, lqa, Debos and deps, LAVA v2, OBS 2.7, ostree-push and jenkins-job-builder:
