Agent edits resulting in "command failed; retry without sandbox?"

[AdrianNO1]

Recently edits have started failing inside the sandbox and it doesn't give me any useful information as to why this is happening or how to fix it. It simply sends me a request like this:
"""
Would you like to make the following edits?
Reason: command failed; retry without sandbox?
"""

What I like about Codex is that I don't need to baby sit it due to the sandbox

Not sure if the thread id was automatically added here, but it's 019c995e-593d-7b13-bd39-b97a9f7409c9

Looks like the github issue link I was given by codex does not set the template to bug report and include the thread Id like it should have: When I enter this link I just get a blank template

Is this a known issue?

Update: The issue mas magically and mysteriously dissapeared. I won't close this issue because I still think it should have logged a clearer error message as to why it failed, so I would have been able to resolve this myself without a miracle.

"command failed" is not a clear enough error message.

I have this exact issue. Codex CLI on Windows 11. It keeps failing to edit a file and asks permission to try without sandbox. Every time I select Always and it still asks again for the same file next edit.

This is happening for me in Ubuntu 24.04 cli since today's update. using full permission via /permissions does not help
Downgrading to v0.114.0 solved this issue for me. I believe there are some degrations in 0.115.0.

Edit: v0.116.0 fixed this issue for me. but this version requires bubblewrap to be enabled (it is now enabled default if /usr/bin/bwrap is available).

Agree with comment above. It is happening for me too, in Ubuntu 24.04 since 0.115.0

Exact same issue since Ubuntu 24.04 0.115.0

Got the same issue on Ubuntu 25.10 starting with 0.115.0 - this makes Codex pretty much unusable right now.

Yes, Ubuntu has also recently experienced sandbox failures
