Delete the RED command you have added under [mlat]]  as per my previous post,  then reboot Pi,  then check status. L

Seems mlat-client installed from RB24 site (using command sudo apt install mlat-client) has some defect. Better purge it, then build & install from source code

(1) First purge existing package

Code Select Expand


sudo apt purge mlat-client



(2) Install dependencies and tools required to build package from source-code

Code Select Expand


sudo apt update -y
sudo apt install -y git curl build-essential debhelper python-dev python3-dev


(3) Downloaded source code and build mlat-client's installation package.

Code Select Expand


cd
git clone https://github.com/mutability/mlat-client.git

cd mlat-client
sudo apt install -y dh-python
sudo dpkg-buildpackage -b -uc



(4) Install newly built package by following command

Code Select Expand


cd
sudo dpkg -i mlat-client_*.deb

Will this not break me Mlat with other services?

Will this not break me Mlat with other services?

No, it wont break your other feeders. The reason is that there are THREE (3) INDEPENDENT mlat-clients installed on your Pi. These 3 work independent of each other. If any one of these is removed or replaced, it will affect mlat of only that feeder for which it was installed. Other feeder's mlat will continue to work normally.

(1) Location of fa-mlat-client binary installed for Flightaware (installed automatically during installation of piaware)

Code Select Expand

/usr/lib/piaware/helpers/fa-mlat-client 


(2) Location of mlat-client binary installed for Adsbexchange (installed automatically during installation of Adsbexchange feeder)

Code Select Expand

/usr/local/share/adsbexchange/venv/bin/mlat-client 


(3) Location of mlat-client binary installed for Radarbox24 (installed manually by the user: sudo apt install mlat-client OR sudo dpkg -i mlat-client_*.deb)

Code Select Expand

/usr/bin/mlat-client

something went wrong

something went wrong

Oops, there were some minor errors in the commands which resulted in failure to build mlat-client from source code. I have made following corrections in my post for building mlat-client from source code. Now it will work ok.

(1) Changed:
cd /~

To:
cd


(2) Changed:
cd /mlat-client

To:
cd mlat-client

Please try to build and install mlat-client again using the corrected commands below:

Code Select Expand


cd 
cd mlat-client
sudo dpkg-buildpackage -b -uc


cd
sudo dpkg -i mlat-client_*.deb

Thank you very much! It worked!

[abcd567]

Glad to know your problem is solved   :)

When in future any update/upgrade command is run, it will replace healthy mlat-client (which you have built yourself) by the defective mlat-client from RB24 repository.

To prevent this, put your mlat-client on hold by following command

Code Select Expand


sudo apt-mark hold  mlat-client 


The responce to above command will be:

mlat-client set on hold..

Thank you.
Now I would like to figure out why, after some of the previous updates, OrangePi now changes the MAC address after each reboot.

Now I would like to figure out why, after some of the previous updates, OrangePi now changes the MAC address after each reboot.

Very old post (June 2016), but may give you some insight.
