Hi Sergio ! Thank you very much for your time ! To answer your question no ! I didn't knew the existence of this "security_file_priv" before.
I've followed your advice about the /home/adamSQL/Documents directory and created it. I think it almost work but the problem is still here, and I still can't update my OS. I add below the error.log file wich is in /var/log/mysql directory. I don't really know if it can help but I'm trying to give you all the informations I have. Don't hesitate to ask me further informations.
