Thanks Zoran.
My Linux build machine uses Centos 7. I thought I'd done the installation to Python 3.6.5. If this is not Python3 > 3.4.0, then I'm confused. The link I follow for installation is here: https://janikarhunen.fi/how-to-install-python-3-6-1-on-centos-7.html > python3.6 -V Python 3.6.5 >python -V Python 2.7.5 Anyway, I realize what went wrong. I'd Krogoth (a 2016 Poky) running before. Now as I'm migrating to Rocko (a 2017 Poky), I try to solve a Python versioning issue by installing Python only (as above). However, there may be other packages I need to update. After getting latest Reference Manual, download and install latest environment, I no longer have python3 issue. However, the Python version of why Python3.6 won't satisfy Python > 3.4.0 still puzzles me (though no longer blocking me).

So, I have no idea which host distro you are using, but: [1] If Debian/Ubuntu, then: apt-get install python3 If Fedora, then dnf install python3 [2] If Debian/Ubuntu, then: apt-get update python3 If Fedora, then dnf update python3 Hope this helps, Zoran _______ On Tue, May 1, 2018 at 10:43 PM, Raymond Yeung <rksye...@hotmail.com> wrote: > I'd just git cloned Rocko and meta-ti.
