 1. Create the new virtualenv, using ``--copies`` so that there's a distinct Python executable to limit::
 
-    $ sudo python3.11 -m venv --copies <SANDENV>
+    $ sudo python3.12 -m venv --copies <SANDENV>
 
    By default, the virtualenv would just symlink against the system Python, and apparmor's default configuration on some operating systems may prevent confinement from being appled to that.
