If you want to upgrade the userspace flavor on top (like Jammy to Noble for example) it is indeed recommended to start from scratch.
If you want to upgrade the Armbian core components like firmware, kernel and boot-loader, these upgrades are shipped as regular apt package.

@Ikesankom hello, no I didn't test it yet. Actually, I have been busy with other issues and totally forgot to test for the upgrade path.
If you have a bit of patience I may give it a shot in the next few days, probably tomorrow.

Ok then I would first try with a pristine image on a different sdcard if possible, just to understand if the problem is the sdcard itself or something messed up in the kernel
