Login as root and execute the following command:

Hey!
Got this notification too from a Raspberry Pi install...
So at the end of this file, I got

mesg n

We have to change this line to :
test -t 0 && mesg n || true

This message just to be sure we have to replace the original line, and not adding a new one...
Thx
