Add the Deluge Team PPA to your Karmic Software Sources

I like using the latest version of Deluge Bittorent client because it usually has fixes for bugs and improvements over later versions.

Deluge usually updates their version before it hits the official Ubuntu repositories so I always add their Launchpad PPA to my sources after a new Ubuntu install.

Here's the link to the PPA for Deluge Team

Click on link that says Technical Details About This PPA and select your version of Ubuntu. For Karmic I added each of these to my software sources:

deb http://ppa.launchpad.net/deluge-team/ppa/ubuntu karmic main

deb-src http://ppa.launchpad.net/deluge-team/ppa/ubuntu karmic main

Under Other Software tab in Software Sources I always de-select the deb-source link. Those are links to DL source code for developers.

Next, save the key into a text file and import it under System>Administration>Software Sources>Authentication>Import Key File:

When you click on the link for the signing key, it opens another web page. Click on the pub/1024R link on that page to get the key above. Then you just copy and paste the info into a text file and save it for importing later.

More info on adding repositories to Ubuntu can be found in the Ubuntu Community Documentation website here.
