Several months ago I installed Ubuntu 9.04 to my Laptop and now I've forgetten the root user's password (which I myself set!) therefore I cannot login as root.
I remember arranging one more user (in addition to the root user) and I do remember that user and its password, but it's only a normal user I don't know how exactly you call it, desktop user, power user, etc.
Anyway... when I log in as that normal user and try this:
it says it's not in the sudoer's list (and that my attempt will be reported).
The problem is, I cannot exactly remember the root users User Name (UN) either, nor the Password (PW). I 'm likely to remember the PW better than remembering the correct combination of UN & PW, that's why I tried to sudo -i
from the normal user's account, i.e. with the hope of having a chance to enter only the root PW, not the combination of root UN & PW.
So I wonder what can I do now. I don't wanna re-install Ubuntu all over, is there a quick solution to this? Any comments and links to solution are appreciated, thanks.
