Installing under Ubuntu is now extremely easy as of Jaunty thanks to jcfp and other users who have helped. Install using the following commands:
sudo apt-get install sabnzbdplus
sudo apt-get install sabnzbdplus-theme-smpl
sudo apt-get install sabnzbdplus-theme-plush
sudo apt-get install sabnzbdplus-theme-iphone
Then open and edit /etc/default/sabnzbdplus
For older Ubuntu versions, use the custom repository maintained by user jcfp. See this thread for details.
I installed a brand new Ubuntu 10.04 server and ran apt-get install sabnzbdplus and it installed 0.5.0. Am I missing something? The way the download page reads to me is that the extra repository isn't necessary anymore. Am I incorrect?
Thanks very much,
