Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just updated to ubuntu 11.10 and am getting "Your authentication attempt was unsuccessful." I am the only user and am the Administrator, during login on my keyring i set to logon automatically, but it still askes me for my password. So i put in my old one and it works. But when i go to install apps it asks again and nothing works! Also if i go to user accounts and try to unlock or change my password it won't let me! It says under password "None" so what's going on?! I'm new to Ubuntu! Help!
