Just had Ubuntu installed. Now for some reason it won't recognize my password when I want to do something like download a package or install the firewall (gksudo gnome-lokkit). The password works fine when I login on the administrators part but won't accept when I try to do something meaningful. Would wiping the hardrive and reinstalling the OS be the only answer here? I hate to do that as I've spent a fair amount of time uploading CD's.
