Apertis is a Debian 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.
Apertis v2022pre is the preview release of the Apertis v2022 stable release flow that will lead to the LTS Apertis v2022.0 release in March 2022.
This Apertis release is based on Debian Bullseye. It currently ships with the Linux kernel 5.15.x LTS series but later releases in the v2022 channel will track newer kernel versions up to the next LTS scheduled at the end of 2021.
Test results for the v2022pre release are available in the following test reports:
- 2020 Q4: v2022dev0
- 2021 Q1: v2022dev1
- 2021 Q2: v2022dev2
- 2021 Q3: v2022dev3
- 2021 Q4: v2022pre
- 2022 Q1: v2022.0
- 2022 Q2: v2022.1
- 2022 Q3: v2022.2
- 2022 Q4: v2022.3
- 2023 Q1: v2022.4
- 2023 Q2: v2022.5
- 2023 Q3: v2022.6
- 2023 Q4: v2022.7

Updates from Debian Bullseye
This release is the second one based on Debian Bullseye, bringing plenty of upstream updates and fixes.
The reference Flatpak Runtime for Apertis
Starting from the Apertis demo introduced in the v2022dev2 release, the runtime has been refined and polished to provide the reference
org.apertis runtime that application authors can use to distribute their Apertis-based applications on top of any Flatpak-supporting system.
Two variants are provided:
org.apertis.headless.Sdk: A basic runtime with some common libraries that headless applications may use.
org.apertis.hmi.Sdk: A larger runtime for graphical applications, based on the headless one.
The “Creating Flatpak Runtimes and Applications guide covers in detail how the runtimes are built, how custom runtimes can be created and extended and how to build applications using them.
Apply and enforce Ed25519 signatures for Apertis Flatpak packages and runtimes
After the introduction of Ed25519 signatures in OSTree in the v2020dev0 release, Apertis has now extended the support of Ed25519 signatures to Flatpak.
This adds a modern signature mechanism that is compliant with the Apertis Licensing Expectations to ensure that all the Apertis Flatpak applications and runtimes deployed on a system come from a trusted source.
Audio policy to mute song app when switching to video app
Improvements in Wireplumber now allows system integrator and developer to support additional use cases, such as mute audio from a song application when switching to a video application.
A demonstrative policy is now bundled in the Apertis images, providing a starting point for teams interested in defining how their products should manage their audio streams.
Improved license compliance checks
The introduction of the license checks and reporting in the v2022dev1 release did start the effort to ensure that all packages in the
target component had the appropriate source licensing metadata.
With the steady progress over the quarters thanks to the patient and accurate work of the Apertis maintainers in reviewing the many inconsistencies identified, this effort now comes to completion, significantly improving the quality of the bill-of-materials produced by the image building pipelines.
Improved availability of packaging tools for developers
The scrips and tools used by developers when performing packaging activities have been reorganized and are now shipped as part of the SDK, improving the development experience.
BSH SMM S2 PRO board support
Designed by BSH, the SystemMaster S2 Pro is an add-on board which provides
input and output interfaces to a dedicated carrier board. Apertis users can now
run a headless system using the
fixedfunction image, which includes hardware
support for wifi, bluetooth and audio. Check the setup notes for more info.
Build and integration
Scalable monitoring of LAVA jobs from GitLab pipelines
Apertis relies heavily on LAVA to continuously test our deployable artifacts. Every night hundreds of LAVA jobs get submitted to the devices in our LAVA farm from the daily image building pipelines; until now, the submission was done with a fire-and-forget approach since the standard GitLab runners do not cope efficiently with monitoring jobs managed by a downstream scheduler like LAVA.
The introduction of a custom GitLab runner dedicated to monitoring LAVA jobs enables the image building pipelines to keep track of all the submitted jobs efficiently.
Developers can now see the results for each jobs and retrieve the logs directly in the same GitLab pipeline that submitted them, helping them to keep track of the impact of their changes in a close feedback loop.
Upstream Linux LTS version tracking from the packaging dashboard
The Apertis dashboard is the tool that the project uses to stay up-to-date with its upstream distribution, Debian.
This works well for the near totality of our packages, with the Linux kernel being the major exception: accordingly to the Apertis release flow for each new stable release we track the latest upstream LTS version, which means that we are rarely in-sync with the version shipped in Debian.
The dashboard is now able to find available updates directly from upstream in those cases, helping the Apertis maintainer to ensure we always ship the most up-to-date fixes to our users.
Tracking consumption of APT snapshots for long-term reproducibility
The approach Apertis took for Long-Term Reproducibility involves frequent snapshots of the APT repositories.
While snapshots themselves are rather cheap thanks to the design of the APT repository format, their accumulation over time quickly becomes a substantial cost.
The Apertis dashboard has now a dedicated section to track the storage consumption of the snapshots over time, to give maintainer visibility on which releases are consuming the most space, which snapshots carry the most weight and how much space can be reclaimed by their deletion.
Raspberry Pi images tested on LAVA
The Apertis images for Rasberry Pi are now included in the tests run on LAVA paving the way to the official suport of this board.
Documentation and designs
Apertis targets a global community developing global products, and this necessarily makes it interact with the legislation regulating the export of goods, software and technology.
The Export controls concept document tries to address the requirements and challenges that teams targeting global markets will face, providing a high level overview of the tools and workflows that Apertis can provide to make such compliance processes easier for them.
The Apertis team has surveyed the On-Screen Virtual Keyboard state-of-the-art in the Wayland ecosystem to evaluate the viable options.
Due to licensing challenges and the in-flux state of the specifications no immediate winner emerged from the evaluation, but a strategy has been defined to address this need in the near future.
Deprecations and ABI/API breaks
No known regressions.
No known deprecations
No known breaking changes are part of this release.
