Same issue here.

Tried installing it inside a Docker devcontainer for .NET 9 (mcr.microsoft.com/devcontainers/dotnet:1-9.0-noble), which is based on Ubuntu 24.04, and it ended up stuck at Cleaning up old npm installations....

To replicate:

• Run docker run -it mcr.microsoft.com/devcontainers/dotnet:1-9.0-noble /bin/bash
• Switch to a non-root user by running sudo -i -u vscode
• Start the native install using curl -fsSL claude.ai/install.sh | bash

Happens to me inside a fresh debian:latest docker container. The system never touched npm whatsoever.

Steps to reproduce:

$ docker run --rm -it debian:latest bash
root@4a035f0b9ee4:/# apt update && apt install -y curl ca-certificates
...
root@4a035f0b9ee4:/# curl -fsSL https://claude.ai/install.sh | bash

Cleaning up old npm installations... [FROZEN]

Facing the same problem on MacOS.

To reproduce:

curl -fsSL https://claude.ai/install.sh | bash

Same issue here, the installation procedure is stuck at:

Cleaning up old npm installations...

Seem to currently be broken on latest. Altho installing fixed version (curl -fsSL https://claude.ai/install.sh | bash -s 1.0.58) doesn't work either.

I tried to installed the stable version - also not working :(

Fixed in 1.0.70
