Hi, Thanks for answering.
I haven't modified the /etc/sudoers file, in reallity, I'm trying to modify it and am getting the same error message. I logged as root, tried with sudo -i, and su, but I'm getting the same message in them all. I also tried to chown, and it didn't work also. I'm not really understanding what is blocking the access to the file.
