Copilot not working in vs code under cachyOS

[tomwaitforitmy]

I do not know if this is a vs code/copilot issue or a cachyOS issue. Therefore, I will post in two places and keep both up to date. I have copilot in vs code running on a couple of windows machines. So it is not a generic issue.

• Copilot Chat Extension Version:
• VS Code Version: 1.105.1, 7d842fb, x64
• OS Version: cachyOS 24.12
• Feature (e.g. agent/edit/ask mode): set up
• Selected model (e.g. GPT 4.1, Claude 3.7 Sonnet): not applicable
• Logs: I couldn't find any logs so far. ~.copilot\ does not exist.

Steps to Reproduce:

1. Install vs code on cachyOS via sudo pacman -S code
2. Start and try to use copilot
   ">" button doesn't do anything.
   "Set up Copilot" button doesn't do anything.
   Settings are unavailable.

AI and other online sources keep telling me to restart VS code, reinstall the extension and re-authenticate with github. However, there is no extension to install.

And I am authenticated and can push into my repo at github. I even refreshed my auth and rebooted the computer two times. Nothing works. What else can I try?

Update: I have this repro on another fresh cashyOS installation with different hardware. Just installed cachyOS and sudo pacman -S code. All the buttons of Copilot don’t do anything.

Just linking the community post that you reference which states this happens due to OSS builds https://discuss.cachyos.org/t/copilot-not-working-in-vs-code/17540/6

We have meanwhile updated the product.json with the defaultChatAgent properties, so the buttons should work to a certain extent: we cannot put the marketplace URL into the OSS build, so you will eventually get this error:

That's great news. What is retry button for? As far as I understand, the user has to install the MS version to see any change? This button suggests that he can come back tomorrow and has a new chance.

Why not tell the user that he has to install another version of VS code?
