"Codex could not find bubblewrap on PATH. Install bubblewrap with your OS package manager. See the sandbox prerequisites: ... Codex will use the bundled bubblewrap in the meantime."

I think neither the bundled bubblewrap nor the Ubuntu 24.04 bubblewrap works properly under Docker with the default options ... Yes, I've just tested that by asking Codex to "Test that bubblewrap is working properly" and then "Test again" after apt-get install bubblewrap.

EDIT: So the solution is to run "codex --dangerously-bypass-approvals-and-sandbox" in a Docker container?
