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 v2023dev1 is the second development of the Apertis v2023 stable release flow that will lead to the LTS Apertis v2023.0 release in March 2023.

This Apertis release is built on top of Debian Bullseye with several customisations. It currently ships with the Linux kernel 5.15.x LTS series but later releases in the v2023 channel will track newer kernel versions up to the next LTS.

Test results for the v2023dev1 release are available in the following test reports:

Release downloads

Apertis v2023dev1.0 images
Intel 64-bit fixedfunction hmi base SDK SDK
ARM 32-bit (U-Boot) fixedfunction hmi
ARM 64-bit (U-Boot) fixedfunction
ARM 64-bit (Raspberry Pi) fixedfunction hmi

The Intel fixedfunction and hmi images are tested on the reference hardware (MinnowBoard Turbot Dual-Core), but they can run on any UEFI-based x86-64 system. The sdk image is tested under VirtualBox.

New features

Completion of the GPL-3-free modernization

This release completes the modernization of the approach to licensing expectations compliance started with the v2022dev2 release.

The v2022.0 release already addressed the licensing challenges in the TLS stack, Coreutils, and GnuPG and this release addresses all the smaller challenges identified in the GPL-3 Deltas Assessment, in particular the move to rust-findutils and libedit.

Build and integration

Build-test packages on OBS before merging

A new feature of the CI for packaging is the inclusion of OBS build test on branches to be merged. Thanks to this addition, now developers can confirm that their changes successfully build in OBS before being merged in the main branches.

Improve developer experience while importing packages

The infrastructure around Apertis has been improved in order to make the importing of new packages straightforward, by avoiding as much as possible any manual steps. With these changes the effort invested to import new packages has been reduced drastically and the possibility of errors in the process has been notably reduced.

Automated note importing in QA Report App

The QA report app is the tool used to collect and summarize the test results for all the Apertis images. To improve the user experience for testers running manual tests and to reduce the amount of information introduced, now the results notes are automatically propagated from previous submissions, giving the chance to the user to amend them to match the current results.

Documentation and designs

Thin proxies - REST APIs

This release includes a concept document [Thin proxies: REST APIS]({{ < ref “thin-proxies.md” >}}) with guidelines for developers to access system APIs through high level REST APIs. Using this approach the complexity of system APIs can be hidden and developers can chose the language/technology that better fit their needs.

Documentation refresh to match the switch to Flatpak

Continuing with the effort of updating documentation after switching to Flatpak, this release also includes a reviewed version of several documents related to the Application Framework to provide developers with the best practices to build their applications.

Deprecations and ABI/API breaks


No known regressions.


No known deprecations


GPL-3 replacements revamp on target images (HMI and FixedFunction)

The obsolete findutils-gplv2 and readline5 packages are not longer available in the target packaging repositories.

The HMI and FixedFunction images now use the rust-findutils tools and the API-compatible libedit to be compliant with the Apertis licensing expectations while avoiding unmaintained forks of GPL-3 components.

See the GPL-3 Deltas Assessment document for further details.


Apertis Docker images

The Apertis Docker images provide a unified and easily reproducible build environment for developers and services.

As of today, this includes the apertis-base, apertis-image-builder, apertis-package-source-builder, apertis-flatdeb-builder, apertis-documentation-builder, and apertis-testcases-builder, Docker images.

Apertis infrastructure tools

The Apertis v2022 infrastructure repository provides packages for the required versions of ostree-push and ostree for Debian Buster:
