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:

    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 can you try rm -rf ~/.cache/opencode and then try again?

    @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
