Hi Roland,


I've committed the patches from #13567 and last nights master builds 
have completed OK. Even Focal, which has been failing since python2 
support was removed in Focal a week or two ago, build OK :). Thanks Roland!


As for the script Bill is probably the one to ask about that. My 
personal opinion is we should be encouraging users to switch to using 
the python3 bindings, the latest  version of most/all? distros are going 
to remove support for python2 so they wont have much choice soon. Maybe 
add your script to the wiki but make it clear it's only a short term 
solution that wont work in the near future?
