Hello, dear Plonists,
'Google Analytics' fails to install under 'Site setups -> Modules' and returns an error message. Here is its text traceback (I receive the same type of error message when trying to install other add-ons, such as the 'webcouturier.dropdowmenu' add-on):
Traceback (innermost last):

I am running Plone5 on a Virtual Private Server (VPS) with Ubuntu 18.04. I also would like to install the 'Open Web Analyser' (instead of Google Analytics). Any hint or advice in either or both of these issues would be very much appreciated.
