This is in Beta testing, but as for me everything works, and it solves a tone of problems with my projects.
One of the most important things is that I can now use MONGO DB with current bug free version, that was not possible with 32 bit systems.
Hope this post helps others who need 64 bit system easy to install, ready to go, and cannot use raspberry official system because lack of 64 bits support and problems with getting some 64bit only tools working .
This solves this problem.

Preinstalled server image for Raspberry Pi 3 (64-bit ARM) computers (preinstalled SD Card image)
The Image is 457 MB, and the system works just after flashing without any black magic to configure

http://cdimage.ubuntu.com/releases/18.0 ... pi3.img.xz
All said, this means the Ubuntu Arm Server image is ready to use immediately upon writing the SD Card and booting the Pi!
Just extract the image from the archive,a nd burn it to SD card.
Than It takes some time to first boot (it makes first configuration) next boots are smooth and fast.
Thanks to the efforts of the Ubuntu Arm team in creating this new ready-made image, no advanced knowledge of the Linux build process is required, and even casual Raspberry Pi users can be up and running easily!
This image is fully intended to be a 64-bit Ubuntu Arm Server platform!

Use cases such as File or Print servers, DNS, MySQL or other database servers, web front-end caching, or other lightweight services all make sense for this platform. It can also be used for installation and testing of Aarch64 software, developing and compiling Arm64 applications, exploring containers, or even production workloads where possible! Small, distributed compute workloads, IoT services, Industrial Internet of Things, environmental monitoring, remote compute capacity in non-traditional settings, or many other uses cases are all possible.
While a desktop *can* be installed, due to the limited memory on the Raspberry Pi, only a lightweight desktop like LXDE or XFCE will truly work, with both Mate and Gnome quickly running out of memory, moving to Swap, and then slowing the system to a crawl.
Even so, desktop performance in this image is not optimized, so sticking with the intended use of this image as a Server OS makes the most sense.
This is intended to be "SERVER" system !

Have fun !
THANK YOU CANONCAL DEVS !
