Unable to sudo or authenticate after passwd -d

[dstojek]

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.

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
