TL;DR: (Scroll down to bottom two questions)

I have found dozens of "solutions" on the Raspberry Pi 3B which have worked for people and not with my 3B+.

I suspect that there is a very specific problem with the "+" version, due to Ubuntu's wiki (https://wiki.ubuntu.com/ARM/RaspberryPi) stating:

Raspberry Pi 3 B+ (2018) functionality is not yet available with these images.

Raspberry Pi 3: ubuntu-18.04-preinstalled-server-armhf+raspi3.img.xz (4G image, 296M compressed) Updated 2018-04-28 (18.04 LTS)

Raspberry Pi 3: ubuntu-16.04-preinstalled-server-armhf+raspi3.img.xz (4G image, 252M compressed) Updated 2018-04-21 (16.04.4 LTS)

I have followed numerous guides on the 3B and a few guides specific to the 3B+ (not the 3B) and none of them have worked. I have flashed several "special 3B+" images onto my SD card and nothing works.

I have tried three different brands of cards, a total of 10 cards. I have tried four different USB power adapters ranging from 0.5A to 3.5A.

The furthest I have gotten is constant rainbow screen, although 90% of the time there was no HDMI signal (100% failure with the latest firmware from GitHub, which is really confusing to me).

As for the other indicators: Red light is constantly on (when powered). No other indicators on the Pi. When I did plug other devices in: Keyboard does not light up (even on powered USB splitter), LAN lights both dimly lit but DHCP never sees anything in that port.

I literally have setup two virtual machines to assist in my efforts, I have compiled all kinds of different projects including the u-boot for ARM in both 32 and 64-bit.

After spending two days (over 30 hours) working on this, I come with two questions:

1: Is it possible to get Ubuntu Server (64 bit) onto my Raspberry Pi 3B+?

2: If so, what are the specific steps?

I would really appreciate any help - I usually do not have problems like this.

  • And yes once I get it working, I will post the specific steps here - I will try to upload any hard-to-find files (e.g: uboot arm64) for anyone else to reuse as desired Oct 3, 2018 at 6:39

    functionality is not yet available with these images - perhaps eventually the good folks at Ubuntu will get things working with 3B+ - maybe in 18.10? Oct 3, 2018 at 12:27

Since the release of Raspberry Pi 3B+ in March 2018 it seems that Ubuntu does not update it images with the new drivers the new hardware need. Look also at Why am I getting a rainbow screen and flashing red PWR LED with a new Raspberry Pi 3B+?. Obviously Ubuntu does have much interest to support Raspberry Pi. You should consider to change the operating system. I suggest to use Raspbian. It is also based on Debian like Ubuntu and it is the operating system official supported for the Raspberry Pi.

  • However they appear to have no intention of providing a 64-bit Debian. Only 32-bit.
