Exec format error on aarch64

[CrazyDubya]

I am encountering an 'Exec format error' when trying to run the Copilot CLI on an aarch64 system. The pre-built binary from the npm package and the GitHub releases is not compatible with my kernel. I have tried all the standard debugging steps, including checking permissions, libraries, and SELinux. The issue persists even with SELinux in permissive mode. It seems that the pre-built binary is not compatible with my system. Kernel version: 6.12.0-103.40.4.2.el9uek.aarch64

👋 Hi @CrazyDubya, thanks for reporting and sorry for the difficulty here. I'm trying to reproduce this issue, but so far haven't been able to on ubuntu:latest:

$ uname -a
Linux 33739899c084 6.12.54-linuxkit #1 SMP Tue Nov  4 21:21:47 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

Could you share more details of the error you're getting and the OS you're using? If there are logs in ~/.copilot/logs that could be helpful as well. Thanks!
