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 v2022dev0 is the first development 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 built on top of Debian Buster with several customisations and the Linux kernel 5.9.x series until the 5.10.x LTS series is released.
Test results for the v2022dev0 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

target images are tested on the

but they can run on any UEFI-based x86-64 system. The
sdk image is
tested under VirtualBox.

This release begins the journey that will lead to the v2022 stable release in March 2022.
The large part of the new changes in this quarter have also been landed in the v2021pre release, with the v2021pre release notes describing them in detail.
Dynamic KVM/UML backend selection in Debos
During the v2021dev1 release cycle an alternative backend for the Debos image builder using UML rather than KVM was developed to make our build pipeline more cloud-friendly, since KVM is often not available on machines provided by cloud providers. Unfortunately UML is by design quite slower than hardware-assisted KVM and this introduced a performance regression for developers using machines with KVM virtualization available.
In this cycle the UML backend was landed to the upstream main branch, adding automatic backend selection: Debos is now able to use KVM if available and fall back to UML in other cases without any user intervention, giving the best performance available.
Deprecations and ABI/API breaks
Loop device issues with kernel 5.9
Due to the lateness of the 5.10 LTS release, this release still ships version 5.9 of the Linux kernel, which has shown a few regressions with loop devices impacting the ability to use offline bundles for the Apertis update manager.
Experiments with the 5.10 release candidates seem to indicate that the issues have been addressed, and a minor update to the v2022dev0 release is thus planned in early January to ship the 5.10 kernel once it is released.
Mildenhall HMI flickering
Enabling hardware acceleration for the graphical stack on the i.MX6 images is now causing visual glitches in the Mildenhall HMI while the AGL compositor is not affected.
As a workaround it is possible to disable hardware acceleration when using the Mildenhall compositor:
sudo sed -i -e 's|Exec=/usr/bin/mildenhall|Exec=/usr/bin/env GBM_ALWAYS_SOFTWARE=1 /usr/bin/mildenhall|' /etc/xdg/user-session-launcher/session.launcher
OSTree offline update bundle format change
libostree 2020.7 version supports two different formats for
static delta bundles, as used for offline updates: the old one without signed
metadata and a new one which also signs the superblock metadata to ensure it
can be trusted.
Support for signed metadata was first introduced in Apertis with the v2021dev2 release and was later upstreamed.
However, during the upstreaming process the format has changed and Apertis now aligns to the upstream format.
This means that signed bundles created with the OSTree version from the v2021 development releases won’t be accepted by this release.
Missing support in the updater for the new OSTree signed offline update format
This release ships with a new
libostree upstream version supporting signed
metadata for offline bundles, but the Apertis Update Manager (AUM) lacks a few
fixes to accept signed offline update bundles generated with it.
An update is planned in early January to fix this issue.
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.
No known breaking changes are part of this release.
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 infrastructure tools
The Apertis v2022 infrastructure
provides packages for the required versions of
ostree for Debian Buster:
deb https://repositories.apertis.org/infrastructure-v2022/ buster infrastructure
Image daily builds, as well as release builds can be found at https://images.apertis.org/
Image build tools can be found in the Apertis tools repositories.
The Apertis Image Recipes provides an overview of the image building process and the involved services.
