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 v2025dev0 is the first 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 6.6.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 v2025dev0 release are available in the following test reports:

New features

Include builddeps reports

Following the idea of provide more resources for Software Build of Materials, now Apertis provides a report for the build dependencies of every package in the target images, including its version. This information helps to easily track CVEs that might potentially affect Apertis packages.

Support for running integration tests on MRs

Following the guidelines described in the Apertis test strategy this release provides initial support for running automated tests on LAVA in the context of a MR. With this feature, packages changes can be validated by running integration tests before landing them to main branches.

It is currently recommended that only packages where potential regressions may have a high-impact on the system stability have this feature enabled, given the extra resources required to run the tests.

As before, all available integration tests are also run regularly on daily image builds.
