Hi You should try to do: nano /etc/apt/sources.list and uncomment all the line. I think it's can unlock the situation

You forgot something that i test, you can launch it directly. You just need to add this in the repository /etc/rc.local before the line "exit 0" /bin/bash /etc/init.d/extract_mac.sh If you do this, the script will launch automatically if the MAC didn't correspond, and if they correspond then he will don't reboot so you don't have to launch it manually if you had these line.

this is very coded with foot, but its working thanx you
