I got same issue on Banana Pi M2 Zero / Ubuntu 20.04 (Armbian)

I install arduino-cli on Armbian. The hardware is Banana Pi M2 Zero.

I use a micro-USB hub to connect a arduino Nano. And it seems detected the board (USB driver is CH340)

I didn't installed any library yet, just installed arduino-cli and then executed the board list command. Then I get an error message:

I found the root cause, the .arduino15/packages/builtin/tools/mdns-discovery/1.0.5/mdns-discovery needs /lib/ld-linux.so.3, but in my target system, the name is /lib/ld-linux-armhf.so.3. So you need to create a symbolic link.

$ sudo ln -s /lib/ld-linux-armhf.so.3 /lib/ld-linux.so.3

I'm getting the same error with an M1 Mac without Rosetta 2 installed. I'm trying the native arm64 version of CLI from nightly builds and homebrew installation, and both throw the same error.
