Comment 84 for bug 453444

-17 is in proposed, not in the official repo yet.

To install it you would need to add karmic-proposed to your list of supported repositories.

You can do it either via a GUI (e.g. synaptic) or by directly adding the following line to your /etc/apt/sources.list

     deb http://us.archive.ubuntu.com/ubuntu/ karmic-proposed restricted main multiverse universe

Hope this helps.
