Upgrade to 4.1.1 landed me with a big problem

[J.L. Blom]

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).

As the message says, do you have a competing process running? 

Try running the command

lsof /dev/ttyUSB0

to identify all programs claiming your serial interface.

Well I've tried a lot of things but I think there is somewhere a
programming error (or error in the config file) as whene trying to run
weewxd th following is the result:

__________________________________________________________
In the configobj.py routine some variable is unspecified meaning it
isn't available where it is expected so wonder is this a program error a
config file error or a compile error and what is the best way to solve
it. Is recompilation the best solution and what do I have to remove
before compiling as many subroutines are recompiled but others not. (You
can see I'm not very familiar with Python).

[Tom Keffer]

The station type is not specified in your weewx.conf file. Looking at your stack trace, it appears that you are trying to run weewx directly from the download directory without installing first. Hence, it does not know what kind of station you have.

If you are using the setup.py install method, make sure you follow the install directions.

No. Forecast does not automatically update.

You will have to download the latest version. Basically, just reinstall, following the directions on the wiki: https://github.com/weewx/weewx/wiki/forecasting

I didn't know that. But does it mean I have to update it from the site?
I thought it automatically came with the new version.
(sorry I was a little slow: social obligations!).
