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:

```bash
sudo apparmor_parser -r /etc/apparmor.d/cursor-sandbox

```

1. Restart Cursor

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

```bash
ls /etc/apparmor.d/ | grep cursor

```

The team is aware of the issue, and your report helps us prioritize. Let me know if the workaround helped.
