Changed user password, now no password works

Asked by Clifford Reynolds on 2013-08-17

In Ubuntu 12.04 LTS, I changed my user (administrator) password from a 4 digit number to an 8 digit number. Then I changed the login to no password. When I tried to update software on the Synaptic Package Manager, the old, the new, and blank passwords did not work. Now I can't change anything because no password works, though I can log in to Ubuntu using no password.

I had recently updated programs using both Synaptic Package Manager and Update Manager.

Yes, no password at all is not an option in Ubuntu.
Autologin is another thing and it's OK.

First you can try:

Open a terminal (CTRL+ALT+T) and issue the following command

    passwd

it will ask for the old password, you just hit ENTER (blank). Then write a password twice and the system should be OK.

IF NOT , you can follow another procedure as it listed in following URL

Thanks, NikTH, the first solution worked just fine. You made my weekend.
