Many thanks to you ErnieePantuso. I am a beginner that confronted this very issue, and your solution was so appreciated. Just for the record, I am a noob, now successful in installing:
Armbian 23.8.1 Jammy Current 6.1.5.0 and after update and upgrade, arrived at Armbian 23.11.1 on 6.1.5.0 on a S905X3 android box (A95XF3 Air). I had problems finding a u-boot.ext that would work, and the two different Armbian sites made it a little confusing since they use different install techniques. I know this thread is old, but still useful.
