Environment
- Surface: Linux app
- Codex version: Last night’s update
- OS and IDE/browser, if relevant: Ubuntu 26.04
- Model and plan or API-key authentication: Pro
Bug
The update to the Linux app from last night causes Codex to hang. It appears to be making a call to Github and encountering a Cloudflare challenge page and then it stops and just keeps on trying. This was debugged with the help of ChatGPT (in a browser) by running the app in a terminal and capturing the errors.
I purged last night’s version and reinstalled the previous version, and it worked again.
Reproduction
Type Hello or anything else into any codex chat. Chat GPT is not affected.
Diagnostics
Linux ChatGPT app
→ normal ChatGPT works
→ Codex spins forever
→ /usr/bin/git exists and PATH is correct
→ Electron reports a network failure
→ ChatGPT endpoint returns Cloudflare challenge HTML
→ Electron subsequently reports RequestError
That is enough that I’d now treat a Linux-app/Codex networking regression as the leading hypothesis, rather than a problem with your Chisimba repository or Ubuntu Git configuration.
