What's Wrong?

Trying to run the installation command on a GNU Guix machine with an i3-N300 CPU (x86_64), I got an error that is not very informative:

$ curl -fsSL https://claude.ai/install.sh | bash
Setting up Claude Code...
bash: line 151: /home/mat/.claude/downloads/claude-2.1.68-linux-x64: cannot execute: required file not found

The file is present:

$ ls .claude/downloads/claude-2.1.68-linux-x64 
.claude/downloads/claude-2.1.68-linux-x64*

Executing this binary manually results in the same error, but it doesn't tell which file it's failing to find.

Not sure what to do. The same worked fine on another GNU Guix machine with an i7 1195G7 Intel CPU.

What Should Happen?

The installation should proceed or at least provide a more meaningful error.

While these issues may indeed be related, especially as I use Guix which is pretty close to NixOS too, I don't think any of them were about a similar error message so it might be a bit too early to classify them as identical. Also, I have another Guix machine where the Claude installation seemed to work fine.

[Edit] But I just tried again with that other machine and now I get this:

$ curl -fsSL https://claude.ai/install.sh | bash
Setting up Claude Code...
bash: line 151: 23393 Segmentation fault      "$binary_path" install ${TARGET:+"$TARGET"}

And Claude no longer works on that machine. I have tried downloading older versions (until 2.1.58-linux-x64) and they no longer work. I'm puzzled, I'm not sure whether the installation method since I initially installed Claude changed, and I can't find a way to check which version I had back then.

Note that using a Debian distrobox and running the installation script in it works; else I always get a segmentation fault (I tried more than 20 versions), so it most definitely relates to supporting distributions like Nix and Guix.

Getting the same error in a Debian Trixie LXC on Proxmox PVE 9.

bash: line 151: 713 Killed "$binary_path" install ${TARGET:+"$TARGET"}

Problem:

Errors on line 151 are CPU instruction.
