Bug Description

On a Kubuntu 26.04 box, in Warp terminal, the hermes installer seems frozen at timeout 600 npx playwright install --with-deps chromium, and <kbd>Ctrl+C</kbd> doesn't interrupt it.

Steps to Reproduce

  1. wget https://hermes-agent.nousresearch.com/install.sh
  2. mv install.sh hermes_install.sh # inspect script
  3. bash hermes_install.sh

Expected Behavior

  1. Progress during SSH clone (only progress when cloning via HTTPS is displayes), to avoid a first impression of the installer hanging.
  2. Progress or the ability to interrupt the "Installing Playwright Chromium with system dependencies" step.

Actual Behavior

$ bash hermes_install.sh

Operating System

Kubuntu 26.04

Python Version

Not in path. python3 returns Python 3.14.4 but the Hermes installer insists on uv installing 3.11 anyway, so not sure this is relevant?
