# Homebrew 6.0 sandboxes Linux source builds with Bubblewrap and aborts when a
# rootless `bwrap` cannot run. The ubuntu-latest image doesn't ship bwrap, and
# Ubuntu 24.04 also blocks unprivileged user namespaces via AppArmor — both must
# be addressed before `brew install`. Install the system package, then relax the
# namespace restrictions so rootless Bubblewrap can create its sandbox.
