Running NCPi on Raspberry Pi 4b, I encountered a package error during apt upgrade which looked very similar to the one described here:
Unfortunately, instead of performing the solution giving there, I rebooted the device, rendering the SD card unbootable.
Is there a way to replicate the actions that the steps following
armbian upgrade
would do “from external” on the SD card to make the existing system bootable again, or do I need to reflash a new image?
