Raspberry PI says this is an UBUNTU problem. Ubuntu says this is a
Raspberry PI issue.
This is the bug.
'/boot/dtb-/bcm2710-rpi-3-b-plus.dtb' does not exist. A symbolic link
cannnot be created with nothing. Also,
/boot/dtb
/boot/dtb-1
/boot/dtb-
cannot be written into. They are all empty.
I have multiple Linux machines. This is the only one which fails to
install Flash Kernel since Nov 20, 2020.
