Recommended action: Install non-setuid bubblewrap from the distro, test with `bwrap --ro-bind / / -- echo working`, and on Ubuntu upgrade apparmor (25.04+ ships a bwrap profile) or install the bwrap-userns-restrict AppArmor profile.
Option: Install non-setuid bubblewrap from the distro, test with `bwrap --ro-bind / / -- echo working`, and on Ubuntu upgrade apparmor (25.04+ ships a bwrap profile) or install the bwrap-userns-restrict AppArmor profile. [evidence: official_recommended_action]
Applies when: Zed Agent terminal tool with sandboxing enabled on Linux (incl. WSL)
Steps:
1. bwrap --ro-bind / / -- echo "working"
2. ls -l $(which bwrap) to check for the setuid bit
3. On Ubuntu: sudo apt install --only-upgrade apparmor, or install /usr/share/apparmor/extra-profiles/bwrap-userns-restrict and reload with apparmor_parser -r.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
