I had a look at the script /usr/sbin/pppoeconf and the reason why it doesn't work is that the zenity support is broken (zenity is an app to show GUI dialogs).
Commenting out lines 22,23,24 makes pppoeconf work again here. I suspect everyone here for whom this script fails has zenity installed. If zenity is not installed pppoeconf will use whiptail or Xdialog for it's dialogs. To fix this pppoeconf should be merged with Debian Unstable's pppoeconf 1.11 which has this (among some other things) fixed. -- pppoeconf prints useless error message, doesn't do anything https://launchpad.net/bugs/54383 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
