Are you using sudo when you do your updates? If so, and you actually want it to require a password, then do this:
Code:
grep -i "NOPASSWD" /etc/sudoers
If it returns with something like this:
Code:
%sudo ALL=(ALL:ALL) NOPASSWD: ALL
Then take out this part, save the file, log out and then log back in:
This will have a final result of this:
Code:
%sudo ALL=(ALL:ALL) ALL
