good evening, I wanted to add a physical network card on my config but when I declare the new network card in the interface and I want to save the configuration it is not taken into account and I have a message following error :
Code

systemctl start 'networking' 2>&1' with exit code '1': Job for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xe" for details.

so i look at the status of the network with the command systemctl and i get:
Code

the network card seems to be well recognized but I do not see what could blame
Do you have an idea 
EDIT :
by testing another configuration I realized that by putting a static IP on the card it crashed the recording of the configuration while putting in DHCP it works well
The problem would come from the static IP.
