RPi3 should be 64-bit as well, but I suspect the proximal issue is that kairos recompiled

elemental-cli

on 32-bit arch, which sets

runtime.GOARCH

!=

arm64

, which causes

GolangArchToArch

to return “invalid arch”.

No idea bout this but doesn't go sets the proper goarch when cross compiling? Like you need to set the goos and goarch to cross compile?

I’m not a go developer, but https://pkg.go.dev/runtime#hdr-Environment_Variables says:

GOARCH, GOOS, and GOROOT are recorded at compile time and made available by constants or functions in this package

Consequently, I presume this means those parameters must be set during cross compilation.
