Hi mactrash,
it would be easier to read the traceback when you format it properly, either by clicking the code button in the editor or using triple backticks before and after the traceback.
I am no Plone user, but what I can see is you use Python 2 and some Python 3 code gets executed. This can't work.
Which os do you use? How did you try to install Plone?
Thanks for your quick reply... I am centos 7.7 and installer with the installer ... try both python 2 and 3 method just bare plone to add-on the install was success... then if run buildout it show such error in the middle
