Not sure if this is board-specific, but filing here anyway. After installing armbian from Armbian_23.5.1_Nanopineo3_bookworm_current_6.1.30.img.xz , apt doesn't find the key for the armbian repository.

I am aware of how to manually add the missing key, but I suppose this should be done by the installation process or be part of the image already.

Hi

You should try to do: nano /etc/apt/sources.list and uncomment all the line.

I think it's can unlock the situation

Not sure what do you mean. In any case, I know how to install the missing key. I am just reporting this as a bug to fix in the image/installation process.
