A while ago I blogged about installing the transmision bittorent client on ubuntu 8.10. Back then, in the days, you had to install transmission and install your own daemon script. But as of Ubuntu 9.04 there’s a package for it!
As easy as:
sudo aptitude install transmission-daemon
Be careful! The paths for the config file and the torrent files are changed. So backup before installing this because you may lose data (like me :().
