Hi, it seems so far only Ubuntu-18.04 is supported on Arm64. Is there any plan to support other versions like Ubuntu-16.04? Quite a few OSS projects are still using 16.04 as their basic Ci environment.
Hello @JunHe77!
Happy to see you checking ARM based builds!
Yes, the Xenial support will be added shortly. We do not plan to add support for earlier versions than Xenial for LXD-based builds though. Hope it helps?
Best Regards
Michał
