we are not really supporting 3.5, we have only 8 packages and
stable is 3.6, so I see no reason to go backwards

I was moving to the next package after installing setuptools and I got

 >>> python36-pip requires: python36 python38 python38-pip 
ca-certificates python36-setuptools
 >>> python36-pip OBSOLETES: python3-pip
 >>> python37-pip requires: python37 ca-certificates python37-setuptools
 >>> python38-pip requires: python38 ca-certificates python38-setuptools


that is very curious and due to

   usr/bin/pip3

that is a copy of usr/bin/pip3.8

Should I manage "pip3" with alternatives so that is really available
for all python versions ?
I can also override with pip3.7 or pip3.6 to force a fixed default.

Marco
