Hi all, Complete Linux noob here and trying to work out where I have went wrong, I bought my one from my mate who had literally switched it on and decided he didn't want it (won it as a prize at work.) He says that he did enter a password when he first got it and today we changed it in the change password setting in options to my new password but when I attempt to install software it asks me for a password and says that the one I changed it too today is not correct? Am I doing something wrong? Message shown as follows: - You are attempting to run "pirut" which requires administrative privileges, but more information is needed in order to do so. Authenticating as "Root" When I enter my password, I dont get an error message, the same dialog box appears again. Thanks in advance for your help!
