Error:

codex-actions also fails on github since 0.54

I'm also running into this issue while running on Codex in WSL on Windows 11. I've downgraded to version 0.53 to work around it.

Same issue on Ubuntu 25.04 - they fully broke the cli today for everybody. Full brick.

What was the problem:

The npm package uses musl-compiled Linux binaries (x86_64-unknown-linux-musl)
WSL2 runs Ubuntu with glibc 2.39, not musl
The musl binary was incompatible and segfaulted
Solution:
Downloaded the codex-x86_64-unknown-linux-gnu.tar.gz (glibc version) from GitHub releases and replaced the musl binary at:
/home/ilya/.nvm/versions/node/v24.7.0/lib/node_modules/@openai/codex/vendor/x86_64-unknown-linux-musl/codex/codex

Thanks for the bug report. We're working on reverting the fix to #6116.

Fix available in https://github.com/openai/codex/releases/tag/rust-v0.55.0 and on npm.
