Tom,
Thanks, I just came into my study and found your reply. I think you're
right, maybe use a new RPi as this one is already 7 years old but I give
it a try with a new Raspbian. Hope I can find tomorrow the time a it
takes a lot of restoring old date as I have now weather data for over 10
years and I will not destroy the time-series.

Honestly, I think you'll save yourself a lot of time by just upgrading
your RPi to Raspbian 10 ("buster"). Security updates for Debian 9
("stretch") were discontinued over a year ago.
Search the web for instructions. Here's an example:

Thanks Tom. I went to the site and I followed the upgrade
instructions
but I assume however that the raspberry OS is unwilling to follow the
rules and gave me the following:
Installing collected packages: pip
Found existing installation: pip 9.0.1
Not uninstalling pip at /usr/lib/python2.7/dist-packages,
outside
environment /usr
Can't rollback pip, nothing uninstalled.

To be honest. my programming days are long behind me (as you can
imagine) and interpreting error messages is a little difficult but
maybe
you can she your light on it.
