2026-07-22 11:13 alpha@alpha-m5:/srv$The warning appears every time Codex starts, regardless of the working directory.
Although Codex continues to function normally using the bundled sandbox, the warning appears to be incorrect because bubblewrap is installed, available on PATH, and no related problems are reported by codex doctor.
However, this report was reproduced on Debian 13 using Codex CLI 0.145.0 with a successful codex doctor --json report and bubblewrap correctly installed on PATH.
even though bubblewrap is installed and available.
Codex should detect the system-installed bubblewrap and avoid displaying the warning.
If Codex intentionally chooses to use the bundled version, the warning should not state that bubblewrap could not be found on PATH when it is actually installed.
This report only concerns the incorrect bubblewrap detection message.
During a previous audit I also observed a one-time sandbox failure, but I have not yet been able to reproduce it consistently, so I am intentionally not reporting it as part of this issue.
What version of Codex CLI is running?
0.145.0
What subscription do you have?

Which model were you using?
gpt-5.5
What platform is your computer?
Linux 6.12.95+deb13-amd64 x86_64
What terminal emulator and version are you using (if applicable)?
OpenSSH session from Windows Terminal to a Debian 13 server (bash). No tmux, screen or zellij.

What is the expected behavior?
Codex should detect the system-installed bubblewrap and avoid displaying the warning.
