Transmission is the default torrent client with Ubuntu. However, I love ktorrent because of the various features it provides. As I use ubuntu and KDE based softwares require kdelibs to be installed, I usually go for alternatives and I found deluge to be a great alternative for ktorrent. It provides similar features as ktorrent.
It can be installed directly via Synaptic but for the latest version, just type in the following in the terminal window. The following instructions apply to Ubuntu 9.04 (Jaunty Jackalope).
I downloaded Ubuntu 9.04 Jaunty Jackalope ISO and discovered that the file was not downloaded properly. It was corrupt. It failed the md5 check and failed to install inside Sun VirtualBox.
I did not want to download the file again. I have a very poor internet connection. I had downloaded the file from http link with the help of wget.
The ISO was the size as specified in the site. I think this process works only if this holds true. Also, it needs to be available in the torrents. These hold true for the file I was trying to download.
