Hello,

I'm experiencing a persistent installation error when trying to run opencode on my Ubuntu system. The installation process fails while attempting to download plugins, and the log consistently shows a JSON syntax error.

I have attached the most recent log file below for your analysis.

This issue might be a duplicate of existing issues. Please check:

  • #2992: Similar BunInstallFailedError during plugin installation on Windows, also encounters registry resolution problems and TLS/CA certificate issues
  • #3082: Program stuck on initialization while trying to install opencode-copilot-auth plugin, same hanging behavior during plugin installation
  • #2341: Error loading opencode-copilot-auth plugin, similar plugin installation failures

The common pattern across these issues is failure to properly install or load the opencode-copilot-auth plugin during OpenCode initialization. Your specific error shows JSON parsing issues when Bun tries to resolve the plugin dependency, which suggests a registry or network connectivity problem.

Feel free to ignore if none of these address your specific case.

@victorserrada do you have some sort of proxy setup?

<!DOCTYPE html>

Looks like there could be some sort of error that is being encountered by install

What happens if you do:

cd ~/.cache/opencode
cat package.json # if empty try: `BUN_BE_BUN=1 opencode install opencode-copilot-auth@0.0.3`
BUN_BE_BUN=1 opencode install
BUN_BE_BUN=1 opencode pm ls
