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 v2022.5 is the sixth stable release of the Apertis v2022 stable release flow. Apertis is committed to maintaining the v2022 release stream up to the end of 2023.

This Apertis release is built on top of Debian Bullseye with several customisations and the Linux kernel 5.15.x LTS series.

Test results for the v2022.5 release are available in the following test reports:
