rpi ubuntu 18.04 arm64 - fix bluetooth not working

apt install bluez hciattach /dev/ttyAMA0 bcm43xx 921600 systemctl restart bluetooth #1

Run AspNet Core 2.2 on Raspberry PI 64bits (ubuntu 18.04 arm64)

As Ubuntu does officially support Raspberry PI 3 (arm64 and armhf) starting with 18.04.2 , I gave a try to the 64 bit version to be able using dotnet core with MongoDB as the later is discontinued in 32 bits architecture. I've downloaded and extracted the 32bits version of  aspnet core as the arm64 is not yet supported. But I've quickly found myself ending with an issue when trying to run the armhf dotnet app: -bash: /opt/dotnet/dotnet: No such file or directory Even if all the dotnet prerequisites were met. A few Googling hours later, I've figured out that, by default, no 32 bits (armhf) libraries are installed. Thought that can be done simply. First allow the armhf repository to be used in addition of arm64: dpkg --add-architecture armhf apt update Then add the armhf flavor of the dotnet prerequisites: apt install libunwind8:armhf gettext:armhf libc6:armhf libssl1.0-dev:armhf You can now enjoy running aspnet core 2.2 apps on a arm64 ubuntu 18.04 :-)
