Talisker,
Ubuntu and Debian use a relatively comfortable system to install / update / remove software. The developers (like Wookey!) package their software into a single file, and put these into some common place, a repository. On your computer you have a program called a package manager, which allows you to search, select, and download those files, and extract and install the contained software. (plus a few more things.) So, in order to use that method, you just tell your package manager (I'll shorten it to PM) on which server to look for packages, and the rest is almost automatic.
Personally I'm using Debian, and I rather use command line tools instead of click and go GUI software.
There is a file in the directory /etc/apt, called sources.list. In order to view the content of that file, you open a terminal window ( Applications --> Accessories --> Terminal ), and type "cat /etc/apt/sources.list"
klaus@laptop:~$ ls -l /etc/apt/sources.list
-rw-r--r-- 1 root root 374 Sep 26 10:15 /etc/apt/sources.list
klaus@laptop:~$ cat /etc/apt/sources.list

This is the content of mine. If you want to use Wookey's packages, you need to add the two lines he gave in his last post. Use an editor like gedit or nano to open the file, copy the two lines into it, and save. NB. See the first line above, the output of the list command. This shows that the owner of the sources.list file is a user caller root. Only root can edit this file. So, what now? You can gain root priviledges by prefixing your command with sudo:
sudo nano /etc/apt/sources.list
Next you tell your PM about the changes:
sudo aptitude update
You can check what owfs packages are available for download now by
sudo aptitude search owfs
And then, get the files and install them:
sudo aptitude install owfs
Replace "owfs" with whatever Wookey has called the package.
And away you are!
After installation, connect the 1-wire adaptor + sensors, and see whether you can find the sensors. "owserver --help=device" will tell you how to invoke the program. I believe you need to run owserver as root, so "sudo owserver -u" will start the program, assuming you've got a DS9490R adaptor.
"sudo owdir" shows the connected adaptor + sensors.
Once you are there, say Piep and we'll see how we get further.
Good luck
Klaus
