RPiBuntu 16.04.1 is now available here.

Besides more recent Ubuntu packages, this image also uses a new U-Boot version that comes with separate binaries for the RPi 2 and 3. In order to upgrade from an older version, remove the old uboot-bin-rpi2 package, install uboot-bin-rpi (which contains both binaries) and change your config.txt:

• comment or remove the line device_tree_address=0x00000100 as uboot now gets the right address from the firmware
• add the following lines at the end of the file:

enable_uart=1

[pi2]
kernel=u-boot-rpi2.bin

[pi3]
kernel=u-boot-rpi3_32.bin

[all]
