Mabe this is too late to help but I had the same problem. My fix was to launch Synaptic Package Manager and do a search for Zenity. When I found the package had been installed I marked it for removal. After that i could open terminal and sudo pppoeconf, entered my password and it configured my DSL connection without a hitch.
-- [Edgy] pppoeconf prints useless error message, doesn't do anything https://launchpad.net/bugs/54383 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
