Just laying out a fact.
Alibaba Cloud, a world’s top 4 cloud providers. Simply could not push out a Debian 12 image after the system was released months ago on June 10th, 2023.
To be fair, they have not released any image updates for any systems after June 2023.
Adding that Alibaba Cloud has replied to my feature request for a Debian 12 image – “Alibaba Cloud will release new OS images in a timely fashion after we evaluate market needs and OS release dates.”
