+    error: Multiple top-level packages discovered in a flat-layout: ['po', 'ui', 'man', 'data', 'virtinst', 'virtManager'].
+    To avoid accidental inclusion of unwanted files or directories,
+    setuptools will not proceed with this build.
+    If you are trying to create a single distribution with multiple packages
+    on purpose, you should not rely on automatic discovery.
+    Instead, consider the following options:
+    1. set up custom discovery (`find` directive with `include` or `exclude`)
+    2. use a `src-layout`
+    3. explicitly set `py_modules` or `packages` with a list of names
+    To find more information, look for "package discovery" on setuptools docs.
