I am only an average user (not into building kernels and stuff). I do have two RockPiS - one with Ubuntu and the other DietPi running. After seing your message, I logged into both the boards and updated them and here are the details if that’s of any use. Just passing it along.

I ran into issues with docker/portainer on DietPI. I then followed this thread ( https://dietpi.com/forum/t/portainer-fails-to-launch-install-or-re-install-solved/15862) and that solved the problem. (Installing and then disabling apparmor)
My personal to-go choice for any arm board is armbian (I buy a board only when I see it on armbian website). But I like DietPi too. Both do a lot of heavy lifting for average users to make their life easy. Just my personal opinion based on my usage
