FWIW, you can still use python2 with weewx4 if you are using the ‘setup.py’ installation method.
If you are on a relatively recent debian version using the apt-get packages, those will default to python3 in weewx v4, so you’ll need all your extensions and drivers to be python3 compliant.
New user of WeeWx and Weatherflow. Installed on Ubuntu 18.04 and I’m getting this error, Any ideas?

Is this a one-off error after hours/days of running normally, or a repeatable failure shortly after starting WeeWX???
shortly after starting, I nuked python3 and reinstalled weewx and the udp driver and I’m functional now. I may attempt installing on a RPi in the next day or so with Python3
Drop me an email at the address in the readme file, and I’ll send you the pre-release Python3 driver…
I have responded as requested.
Should we hold off on upgrading to v4 till the new version is released?
You can always go to v4 and still run python2.7 and you’ll be fine. You can switch to python3 when all the drivers and extensions you use are updated. No rush.
still havent see the updated plugin, did you get my email?
Sorry for the delay. I sent it an hour ago.
FYI, I am finishing up the Tempest-specific docs for the driver now, since WF officially published the new UDP API for it. (Thanks, @corrineb!) I’ll be pushing it up to GitHub in a day or so…
Thanks again!
I figured out what I needed to do to fix my weewx for WU… When they ask for password, what they are really asking for is the ‘device’ key…
As opposed to the section asking for the API key, which is for the wufixer app.
I’m subscribed to the weewx Google group now, but I’m wondering… is there a add-in for uploads to DarkSky? (and other weather services???)…
I do have my connection to CWOP back in, as well as PWS Weather… I’m wondering about others not mentioned by default…
BTW - Hope you’re doing well… enjoy the long holiday weekend as best you can!
Thanks again!
Tony
Some of the community-developed uploaders are listed near the bottom of the WeeWX wiki page:
https://github.com/weewx/weewx/wiki
Search the Google group though, since it seems like uploaders to everything including your kitchen toaster are buried in the archives there.
In case you haven’t heard yet, DarkSky was bought by Apple last month and most of their services are going away…
Thank you… I actually did find some of those resources, @GaryFunk helped me find them!
I have weewx up and running on 4.0, and Python 3 without issues, but then again, I’m only dipping my toes into using weewx…
So far so good!
Thanks! 
Tony
Took a while, but I finally got this up and running on my pi and my Tempest is reporting to PWS weather!!
Anyone with thoughts on why weewx and PWS are reporting different Barometer readings than my Tempest?
@kfite13 PWS Weather is a great weather site to upload your data, but the current conditions are normally at least five minutes behind.
Does this apply???
https://github.com/weewx/weewx/wiki/Barometer,-pressure,-and-altimeter
You’d have to do the math, but see if the difference is the altitude correction. Mine is always off 12 mbar which lines up with my altitude here.
Yeah, I was taking that into account.
pretty sure that is exactly what is going on.
Thanks to both of you.
Hi everyone - I’ve got a problem, and I think it might be with my conf file but not sure and would like some advice. I got WeeWx to work perfect with the Simulator (I see the results in the terminal when I run it manually, and it creates the html files fine). I then installed the WeatherFlowUDP driver, which seemed to be successful, and edited my conf file based on the sample. Basically I copied/pasted and changed the Station ID in the sample to my Station ID, and set the conf file to use it. (I tried manually updating it, and also rebuilt it with the reconfigurations function in case I messed something up, but get the same config file both ways.) When I run WeeWx with the WF driver, I don’t get any results, and when I look at the log file, I see this error: “OSError: [Errno 49] Can’t assign requested address”
