No, It didn't work.
My $LANG is it_IT.UTF-8 , but even if I try to set LANG=it_IT.UTF-8 , will not works.
Now I will try to install LINUX MINT to another new partition for understand if it is a problem of a corrupted S.O. or a language bug.
Hi, I try to run the install from another LAPTOP with UBUNTU 15.04 and from a fresh installation of MINT 17.2 but I have always same error....
Maybe the problem is the language? In the error I read that installation file use the en_US... hope this problem will be fixed soon
