F4HUXAlthough your mlat problem is solved, I am curious to know which dump1090 you are running. From your output below it is clear it is NOT dump1090-fa.
huawei@ubuntu-server:~$ sudo systemctl status dump1090-fa
[sudo] Mot de passe de huawei :
Unit dump1090-fa.service could not be found.
I first thought you are running dump1090-mutability, but the top command screenshot of Ubuntu Server says only "dump1090", does not say "dump1090-mutability.
connection to dump1090 running on ubuntu-server (ip =192.168.0.101)

Can you please issue following command on your Ubuntu Server and post the output?
sudo apt-cache policy dump1090-mutability
