@jock /dev/sda1 4ca8....43ad is a USB drive that is permanently connected to the Tinkerboard, which acts as a second partition and has always been connected even during system updates.
The good drive, the Armbian one, is:
/dev/mmcblk2p1
bfdcf9c9-e3b6-4f2e-a89a-f9d17289d118
which is the one it doesn't find.
