Cursor on Linux doesn’t run on the first try.
You download it, type ./Cursor*.AppImage, you get this:
./Cursor-0.49.5-x86_64.AppImage
The setuid sandbox is not running as root. Common causes:
* An unprivileged process using ptrace on it, like a debugger.
* A parent process set prctl(PR_SET_NO_NEW_PRIVS, ...)
Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted

Trace/breakpoint trap (core dumped)
Being greeted with an error on the first try is not a great UX. The thing is, if you feed this into an LLM, it tells you the solution (–no-sandbox). Which suggests to me that Cursor could be a bit smarter about figuring out how to run itself.
