I just tried to install gnome-apt from "http://www.debian.org/~mblevin/gnome-apt ./", which upgraded apt too, and now everytime I try to use apt-get for anything I get:
E: The method driver /usr/lib/apt/methods/ftp could not be found. And indeed, there seems to be no such file in the new apt package. Where can I get it, and shouldn't it have been in the new apt package? (I have only set up ftp sites in sources.list)
