-!!! warning
-    On Ubuntu, installing only Python3 will not create a symlink for the interpreter at `/usr/bin/python`: scripts need to be called using the `python3` binary explicitly. As a workaround, you can create this symlink using the `update-alternatives` utility:
-
-        # update-alternatives --install /usr/bin/python python /usr/bin/python3 1
-
-    This will allow calling the `python3` binary as `python`.
