During the installation process I was asked to set a password. I chose a password (a strong one) and everything goes smoothly every time I log in. Problems arise whenever I resort to "sudo" or "su" commands ...
I mean, if I type "sudo or "su" I'm compelled to provide a password and whenever I type the password I choose during the installation process I get this error:
Authentication failure
Can someone help me?
Maybe the error comes from the way you use sudo.
Sudo should be used by your regular (non-root) user the following way:
sudo command
When prompted for a password, you should enter your user's password or in other words, the password used at login.
This is known from Ubuntu, you did not set root password.
the password you have set is your user's password and has no relation to the root.
please take a look at this link and see if it can help : http://www.debuntu.org/recover-root-password-single-user-mode-and-grub
P.S : I left ubuntu for good just because of these lame features, I'm a developer and I need to function with everything, why limit me -.-
