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 v2025dev2 is the second development release of the Apertis v2025 stable release flow that will lead to the LTS Apertis v2025.0 release in March 2025.

This Apertis release is built on top of Debian Bookworm along with several customizations and it ships the latest Linux kernel 6.7.x series. Later releases in the v2025 channel will be tracking newer kernel versions up to the next LTS as well as Debian Bookworm Stable Channel.

Test results for the v2025dev2 release are available in the following test reports:

Release downloads

Apertis v2025dev2.0 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 (UP Squared 6000), but they can run on any UEFI-based x86-64 system. The sdk image is tested under VirtualBox.

New features

Improved SBOM for licensing

Continuing with the work of improving the SBOM for licensing, now the report includes license and copyright information for non binary files, such as scripts and configuration. With this new enhancement Apertis’ SBOM provides more accurate information about licensing for the standard images.

Build and integration

Test on MR configuration

Running test on MR has shown to be a key new feature in Apertis, allowing both developers and maintainers to ensure the sanity of the changes before they land. Following this idea different types of test are available, such as package centric, integration and bootstrap test. To improve readability and avoid misunderstandings, the configuration settings were adapted, becoming more natural.

Test on MR for linux

Continuing with the trend on adding test on MR, a set of custom tests have been implemented for the linux kernel. As this is a very special package with delta respect to Debian additional checks are now performed, to ensure that changes proposed by developers don’t cause regression and simplifying the review and test process.

Deprecations and ABI/API breaks


No known regressions.


No known deprecations


Package libgiod v2

In order to overcome limitations in libgiod v1 (1.6.3) it has been upgraded to its new upstream release v2 (2.1-1). This change introduces small API changes that need to be addressed by developers.


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.


Image daily builds, as well as release builds can be found at https://images.apertis.org/
