Error installing x86-64 Arch in OrbStack on Apple Silicon

[evanrelf]

Fresh x86-64 Arch Linux VM created in OrbStack on a 2021 M1 Pro MacBook Pro. First thing I did was run the DetSys Nix installer and got this error:

Error

Here's some more system info:

[evanrelf@arch-x86 ~]$ uname -a
Linux arch-x86 6.9.8-orbstack-00170-g7b4100b7ced4 #1 SMP Thu Jul 11 03:32:20 UTC 2024 x86_64 GNU/Linux

Using OrbStack version 1.6.4 (17192).

Just verified the install works perfect when using the aarch64 Arch Linux in OrbStack, and fails in the exact same way with x86-64 Ubuntu 24.04. So probably something to do with x86-64, maybe related to Rosetta?

You might try this suggestion in a similar issue: https://github.com/DeterminateSystems/nix-installer/issues/955#issuecomment-2099655058

Oops, sorry for the dupe! Thanks, will try that later today 👍

[evanrelf]

Didn't get around to it until now, but I'm happy to confirm that adding --extra-conf='filter-syscalls = false' as suggested here worked!

Would be awesome if this was detected automatically.

If you know of a way to detect running under OrbStack, I'm all ears!

[evanrelf]

I don't know of any official guidance for how best to detect that you're running under OrbStack, but there are lots of signs inside the Linux VM!

• The orb and orbctl executables are in the PATH, and located under /opt/orbstack-guest/bin.
• The kernel release (uname -r) has the string orbstack in it.
• The host filesystem is mounted at /mnt/mac.
