Hey, this is a known issue on Linux. The cursor-sandbox-apparmor 0.4.0 package only installs the profile for remote or SSH, but it doesn’t fix the local cursor_sandbox profile used on desktop. Because of that, preflight fails silently and the Run in sandbox option doesn’t show up.

Try this workaround. Add network unix, to the local AppArmor profile:

  1. Open /etc/apparmor.d/cursor-sandbox and add the line network unix, inside the profile block
  2. Reload the profile:
sudo apparmor_parser -r /etc/apparmor.d/cursor-sandbox
  1. Restart Cursor

If /etc/apparmor.d/cursor-sandbox doesn’t exist, check:

ls /etc/apparmor.d/ | grep cursor
