What's Wrong?

The native installer fails with timeout errors on Ubuntu 22.04, despite curl successfully reaching all required endpoints. The installer times out at two different stages:

1. Initial version fetch - 30-second timeout fetching from https://storage.googleapis.com/.../stable
2. Binary download - 10-second timeout downloading from https://downloads.claude.ai/claude-code-releases/2.0.61/linux-x64/claude

Both endpoints respond successfully to curl commands with 200 OK responses.

The same installer works successfully on Ubuntu 24.04.

What Should Happen?

Installer should successfully download and install Claude Code, as it does on Ubuntu 24.04.
