Yes you’re correct. Unfortunately we don’t have the binary ready for ARM64 right now. However, I have relayed this feedback directly to the WARP product manager.
It might actually be really helpful if you could at least provide a statically compiled binary in addition to the dynamic ones you have for various distributions of linux for the single arm64 architecture you currently support. A static binary would be trivial to run through qemu user mode. This is what I attempted to do on my arm64 platform, but it is difficult because I’m running hirsute and the closest thing you have for me is a focal dynamically linked binary.
