Unofficial Debian packages (Yorick and more)

Introduction

I am the current maintainer of a variety of packages for Debian GNU/Linux, in particular all the Yorick-related packages. I maintain here two repositories:

squeeze-backports: recent packages adapted and compiled to run under Debian Squeeze (= stable, as of writing). I try to support these packages and provide a sane upgrade path. I also try to upload packages for i386, powerpc and amd64.
unstable: experimental packages, compiled for Debian unstable. Use at your own risk, upgrade path not guaranteed.

Please do tell me whenever you find bugs with my repositories (for instance yorick gets uninstalable on amd64 when I update the package on i386 and forget to update it as well on amd64. I appreciate being noticed when that happens). Don't expect too much when using my unstable packages: upgrading from an unstable version to the next may fail or yield unspecified results. In that case, purge the package before installing the next version:
apt-get --purge remove <package-name>

My backports are true backports as in http://www.backports.org. They should be fairly stable, and I try hard to make every upgrade sucessful. Nothing is bug-free, though. Like http://www.backports.org, my repository is marked "no-auto": eventhough the package versions are greater than those on the official Debian/Squeeze archive, my packages will never be installed automatically by default. You have to request their installation explicitely, either using pinning or with the "-t" option to apt-get, as below.

Using this repository

The simple way to use the packages proposed here is to simply browse the pool. Squeeze backports are recognizable by "bpo604" in the Debian revision number. You can install them using gdebi for instance.

You can get the backports by adding the following to your /etc/apt/sources.list:
# unofficial yorick 2.1 packages deb http://thibaut.paumard.free.fr/debian squeeze-backports main contrib non-free deb-src http://thibaut.paumard.free.fr/debian squeeze-backports main contrib non-free and then issuing: apt-get update apt-get install -t squeeze-backports yorick

Likewise, for the unstable repository, add the following to your /etc/apt/sources.list:
# unofficial yorick packages deb http://thibaut.paumard.free.fr/debian unstable main contrib non-free deb-src http://thibaut.paumard.free.fr/debian unstable main contrib non-free

I sign the repository. My public key is in the Debian Maintainer keyring. There are several ways you can add it to the APT keyring so that my backports appear as coming from a "trusted" source. I give here two manners: the easy one, and the safe one (less easily forgeable):

Simple way: download my public key and type (as root):
apt-key add 4B9488F1.gpg
Safer way: install the debian-maintainer package using your package manager (or download it and install it with dpkg -i debian-maintainers_1.47_all.deb) then:
gpg --export --keyring /usr/share/keyrings/debian-maintainers.gpg 4B9488F1 | apt-key add -

Note on specific packages

dpuser, qfitsview

DPUSER is an interactive language that is capable of handling numbers (both real and complex), strings, and matrices. Its main aim is to do astronomical image analysis, for which it provides a comprehensive set of functions, but it can also be used for many other applications.QFitsView is a FITS file viewer. It can display one, two, and three-dimensional FITS files.

I am in the process of packaging them for Debian. QFitsView depends on libxpa1, which has been recently packaged. This library can be found in my squeeze-backports repository to ease installation of QFitsView. It's the exact same file as the same revision in the official Debian unstable distribution.

yorick-av

Yorick-mpeg is a plug-in for making movies (MPEG, DivX...) from within Yorick.
