Comment 2 for bug 830782

We changed the packaging for Deluge recently so that deluge-gtk no longer requires libtorrent which means it can be installed as a client only.

The packaging will need fixed so that Software Centre defaults to deluge rather than the currently set, deluge-gtk. Also when installing only deluge-gtk a patch should be applied to turn off classic mode to avoid this initial error.

To solve the problem in the meantime you can install the package named "deluge" from synaptic package manager or from the command line: 'apt-get install deluge'
