ubuntu-16.04-preinstalled-server-armhf+raspi3.img.xz was flashed for a Raspberry Pi 3 B+. Bootup halts at the rainbow screen:
When the SD card is flashed with Raspbian the system works correctly (hardware is not defective and power supply is good.).
Is there any reason not to expect bespoke 16.04 image not to work on pi-3B+?
