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 


[DZpower]

worked like a charm :)
Thank You so much :) Kudos to your expertise

[abcd567]

Glad to know your problem is solved   :)

[abcd567]

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..

abcd, have you advised Airnav  of their defective MLAT client?  If not are you aware of the defect and I can advise

Alan

[abcd567]

Alan, no, I have not advised AirNav about the defective mlat client because:
(1) up till now only 2 cases have been reported in forum
(2) I cannot make out what is exactly the defecti, is it because of a corrupted files or because of some changes made by RB24 developers in the source code.

If you like you can inform support with links to the two lates threads  on this issue.

abcd
