From test on Ubuntu 24.04:

I've successfully installed Node.js 20 via nvm and downloaded/installed vibetunnel. Here are the key
findings:

Installation Status:

• ✅ Node.js 20.19.4 installed via nvm
• ✅ VibeTunnel v1.0.0-beta.11.1 installed successfully

Issues Found:

1. PAM Authentication Warning: The native authenticate-pam module isn't found, so PAM authentication won't
   work on this Linux system
2. npm_config_prefix Conflict: Had to unset the npm_config_prefix environment variable for nvm compatibility
