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=0x00000100as 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]
