That is the problem. When I create an account without password (Or disable the password on an account that has), when I try to install softwares or when I log out the account, it asks for password.. If I type the old password, it says: "invalid password" and isnt possible to do anything on Ubuntu.. Im using Ubuntu 11.10 !
A long time ago I had to format and reinstall Ubuntu because I disable my account. Now, I have my root account with pass, but the problem still exists when I create other account.
Is there a way to fix that??
Thanks! And sorry if there is any English mistake.. (:
