*Very* good point.  Given that what Michael does is outside of the distro, we
 are lacking some bells and whistles -- and moreover some check and balances
 I get thrown at me from within the distro and its quality checks.

So one thing we had run into was inconsistent versioning  so the "old" PPAs
may have shadowed the new one with the dh-r version wanted -- but 'hidden'
behind a higher version number. (This can happens as the version strings get
expanded with Ubuntu distro strings added etc pp).

So an implicit "reset" by only looking at one pair is a very good ides,

Now why does a serious man like you still run 16.04 though?  ;-)
 
| Thanks to all involved in getting this working and documented.

Our pleasure.
