In Ubuntu I have one normal user root1. And till now when I want to be a root I do:
root1@host:/home/root1$ sudo su
[ sudo ] password for roo1:
type password and I had:
root@host:/root:#
but now I type a password and get
root1@host:/home/root1$
but without info about wrong password or any clue. If I put wrong password I obviously get info about that.
So What is wrong?
