The cli constantly says "command failed; retry without sandbox?" when trying to edit files.

This is the first time I've used codex as I've been using Claude Code.

What steps can reproduce the bug?

Nothing special running here, just trying to get the agent to make some changes. I can see some previously closed Issues with he same issue, but they haven't been closed as "Fixed"?

What is the expected behavior?

It should be able to make edits without failing, or at least have a fallback. The agent itself couldn't see any of these errors or issues. It had no idea I was being prompted and couldn't suggest a fix which also seems strange

TL;DR

The issue may be resolved by retrying the command without sandbox as suggested by the error message, or investigating compatibility issues with Ubuntu 25.10.

Guidance

  • Investigate if there are known issues with codex-cli version 0.118.0 on Ubuntu 25.10, as this could be a compatibility problem.
  • Try retrying the command without sandbox to see if it resolves the issue, as suggested by the error message.
  • Review previously closed issues with the same error to see if there are any workarounds or insights that could help resolve the issue.
  • Consider reaching out to the Codex support team or community for further assistance, as the agent was unable to suggest a fix.

Example

No code snippet is provided as there is no clear code-related issue.

Notes

The issue may be specific to the user's environment or version of codex-cli, and further investigation is needed to determine the root cause.

Recommendation
