Deluge Bit Torrent Client
Deluge is among my favorite bit torrent clients for Ubuntu. It is fast, slick and packed with all sorts of functionalities. Deluge is not available in Ubuntu by default, but its in the repositories.

• Click Here to Install Deluge in Ubuntu from official repositories.

• Now, if you want to install the latest bleeding edge version of Deluge instead, you need to do the following in Terminal.

sudo add-apt-repository ppa:deluge-team/ppa

sudo apt-get update

sudo apt-get install deluge

• Done. Now goto Applications - Internet - Deluge BitTorrent Client.
