You are seeing an error in the "traitlets" package, not really a Leo error.  I just did  a fresh install on Windows, and the code in the traitlets _version.py file is a little different from what your error message shows.  Perhaps you could try updating traitlets to the latest version (5.2.0 on my system).  

This error would only matter if you want to use Jupyter notebooks.  Otherwise Leo should work correctly, even though it is annoying to get the long error message every time you start up.

Thanks for the fast response,

i've got installed python3-traitlets package v.5.0.5-1 (Debian package are a bit outdated)

but on your explanation i feel smooth. Go Leo.

Thanks again!
