Problem with Network Manager Service

Hello.I’m facing some issue with my wi fi connection.I opened my pc and although that i saw that i connected to wifi i had not internet connection.I tried some methods but nothing worked and then i went to the /ect/NetworkManager.conf file and i changed the false option to true,i restart my pc and then the network manager never ran again.I changed again the true option to false as it was but the network did not work.
When i try to start the network manager i receive this message
“networkmanager.service failed because the control process exited with error code”

How to solve this issue?

I used parrot 3.9 x386 archtecture

I installed parrot with Debian GTK

My pc is multiboot with windows 7

Thank you

It’s ok, i just installed the newest version of parrot and the problem solved.Thanks a lot
