Hello Fraenk,

The whole procedure is to add the following two lines:

deb http://otherside.servebeer.com/ubuntu intrepid main deb-src http://otherside.servebeer.com/ubuntu intrepid main

in the following file:

/etc/apt/sources.list

Open the file with your text editor of choice (requires superuser access, sudo or similar) and manually type the lines in, in the end of the file.

As soon as you've done that, the easiest way to add the key is to download it on your computer, say on your Desktop. Then do the following in a terminal:

sudo apt-key add ~/Desktop/key.gpg

sudo apt-get update

Next time you start Synaptic, it should have updated the packages and you should find pd-extended in there.

The only case when this wouldn't work is with the 64-bit version of Intrepid, since the package is a 32-bit one.

Also:

This is the non-repository version. If you can't be bothered with the repository, you can just download the package from there and double-click on it to install. The benefit of the repository is that you get updates as and when needed, you also get access to other software, and when you get the next ubuntu distro, somebody will do a package which will go on the repo so you'll automatically be getting that.

Last but not least:

Marco is providing a mirror for the Otherside website, including the Repositories, SVN and APT. His server is faster than mine, so anyone having download speed issues might want to try his. Mine is located in Sheffield, UK. His is located in Erfurt, Germany. Roman is also hosting the APT repositories in his server, in Switzerland. Roman's is probably faster than mine but busier than both mine and Marco's since it hosts netpd.

So in the three cases, the sources.list entries would be:

deb http://otherside.servebeer.com/ubuntu intrepid main

deb http://otherside.gnufunk.org/ubuntu intrepid main

deb http://www.netpd.org/~ilias/ubuntu intrepid main

The first one being mine, the second one being Marco's and the third one being Roman's. (You only need to use ONE of these servers in the sources.list file)

Thanks again Marco and Roman!
