The SDR dongle works with dump1090 and maps to the browser. Currently picking up six planes.
myip shows ADS-B connected but MLAT not found
The adsb install script threw some complicated python error the first time it ran but redoing the install from scratch (after rebooting) seemed to work but but still ended with;
> No data available from IP 127.0.0.1 on port 30005!
TCPDump shows traffic on port 30005
Let me know if any other info is helpful.

Python 3.12 (or later) is not currently supported. What platform are you using?

Is there any news on this.
When i run the install script i get this error on the MLAT section of the install
”mlat from setuptools import setup, Extension”
I am connected to ADS-B Server but just not with MLAT.
I have downloaded python3.10 and changed environment to work off of that but still wont run.
Little 411 on the system im running
```auto
RTL-SDR v4 -
1090 filter - ADS-B Exchange Saw Filter
1090 Antenna - 5.5dBi 1090/978 N-Type Female Antenna - 26-inch (ADS-B Exchange one)
Pc - Intel Nuc i5 16GB of RAM - Ubuntu v24 (Latest)
Unit has 4 USB-3 Ports and i am only using one for my receiver
In my dump1090-fa config file (/etc/default/dump1090-fa) i have added my Lat/Long
My cpu has a lot of room. 90% of its overhead is empty.
```

It still requires a workaround, like [Debian Trixie: mlat install fails - #10 by dseven](https://adsbx.discourse.group/t/debian-trixie-mlat-install-fails/1204/10)

My understanding is the script can fail because the underlying Linux OS is missing the “build-essential” packages or the Python development headers. Run this command to ensure they are present:
sudo apt-get update
sudo apt-get install -y python3-dev python3-setuptools build-essential
After running that, **restart the ADS-B Exchange install script**.

This script actually worked. I got a few errors while it was installing, but it didn’t affect the MLAT reporting feature.
Thanks for all the help
