I'm trying to install Ros2-galactic in Ubuntu 20.04 version. while Installing I'm facing the following issue.
--- stderr: rqt
error: Multiple top-level packages discovered in a flat-layout: ['share', 'resource'].
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.

I've seen similar type of errors and their solutions,from the following link "Multiple top-level packages discovered in a flat-layout" But unable to slove it. I couldn't find the setuptools in my system to edit the pyproject.toml file and aslo setup.py file. where can I find those files in unbuntu version 20.04, In the system various versions of python is also there
