I upgrade yesterday finally to version 4.1.1 coming from 3.8.2 and ended
in total disaster. Weewx doesn't work anymore (after > 5 years working
flawlessly).
The log (rather long says:

______________________________________________________________________
I haven't programmed in the last 3 years and most of my programming
skills are with FORTRAN an PASCAL ( so you see I'm a rather old user &
programmer). But weewx is used 24/7 and indispensable for me and several
other users therefore I hope somebody can help me out.
One question is do I have to remove all old weewx files except the ,sdb
files and reload the version of weewx also or can I reinstall using the
recently loaded installation file.
Technical background:
Weewx runs on an old raspberry pi, the weather-station is a Vantage Pro
and the network and all systems are Linux (Ubuntu).
