I want Qwen 3.5 running smoothly on my Ubuntu machine. The environment is a standard Linux desktop (22.04 LTS), fully up to date, and currently has only the default system packages installed. Your job is to: • Download and install Qwen 3.5 locally, making sure every dependency is satisfied through apt, pip, or any other reliable method. • Verify the installation by launching Qwen, executing a basic test command, and confirming that the expected output appears without errors. • Provide a concise step-by-step script or README so I can reproduce the setup later on a clean Ubuntu box. Acceptance criteria 1. qwen --version returns 3.5 without warnings. 2. All commands work from a fresh terminal session without sourcing extra files manually. 3. The provided instructions run end-to-end on a stock Ubuntu install. No extra databases, web servers, or dev tool stacks are required right now. If you prefer Docker or virtualenv for isolation, feel free to propose it, but the final result must still be operable directly on the host system. Let me know how soon you can complete the setup and what approach you plan to use.
