There are two ways to get the repository configured: the GUI way and the command line way. I think the command line way is a little quicker, but I’ll give you both. Remember, if you are not running Hardy, you will need to change all instances of hardy throughout these instructions to feisty or gutsy, whichever you are using. Olli did packages for all three versions. If you don’t know which you’re running, go to System > About Ubuntu and read the window that spawns. Your version will be in there somewhere.
First the command line way.
echo -e "deb http://ppa.launchpad.net/daou/ubuntu hardy main\ndeb-src http://ppa.launchpad.net/daou/ubuntu hardy main" | sudo tee /etc/apt/sources.list.d/btnx.list
sudo apt-get update && sudo apt-get install btnx btnx-config
Then, I’d recommend using btnx-config from Applications > System Tools > btnx to configure the tool. You could also do gksu btnx-config
at the command line to bring it up.
Next, the GUI way.
If you already have btnx installed, go to System > Administration > Software Sources. Go to the Third Party Software tab. Click +Add and paste the line for each of the two APT lines: deb http://ppa.launchpad.net/daou/ubuntu hardy main and deb-src http://ppa.launchpad.net/daou/ubuntu hardy main. When you click Close, it will ask if you want to reload the sources. Confirm the reload.
If you do not already have btnx installed, go to System > Administration > Synaptic Package Manager. Go to Settings > Repositories and follow the above instructions. One the list finishes reloading, Search for “btnx” and the two packages will be shown in the main screen. Click each to mark it for installation, then click Apply. When it’s finished, you can access btnx-config through Applications > System Tools > btnx from the top panel.
