    Unable to sudo or authenticate after passwd -d

    While installing Ubuntu I've set my user password which started to annoy me while doing sudo or something. I've decided to remove password with passwd -d user. After that I'm no longer able to use sudo. It asks for a password which I've removed.



    Code:
    damian@damian-laptop:~$ sudo su
    [sudo] password for damian: 
    Sorry, try again.
    [sudo] password for damian: 
    Sorry, try again.
    [sudo] password for damian: 
    Sorry, try again.
    sudo: 3 incorrect password attempts
    damian@damian-laptop:~$
    //solved. I've forgot about simpliest passwd user

    I've got the same problem.

    I deleted the password with
    sudo passwd -d username

    And afterwards every su-commands asks for an password. Neither the old nor an empty password is working.

    What can I do?

    Thanks

    okay I solved it:
    when executing "passwd" without sudo I was not asked for the old password. So I gave me a new one and afterwards I disabled the password in the system settings
