These packages are mostly build for sid/unstable systems with the free Debian GNU/Linux operating system, but should work on any related system such as Ubuntu or similar. You can browse the repository, or just add the following deb-lines into your /etc/apt/sources.list and do an update.
deb http://debian.kironet.de/packages/ ./ deb-src http://debian.kironet.de/packages/ ./ # deb http://debian.kironet.de unstable main contrib non-free # deb-src http://debian.kironet.de unstable main contrib non-free
To allow the gpg digital signature checking with apt >0.6, install the kironet-keyring package first, or fetch the keyring manually:
wget http://debian.kironet.de/debian_at_kironet_de.asc -0- | sudo apt-key add
it is also available on several keyservers...
gpg --keyserver subkeys.pgp.net --recv-keys AC6F31C5 gpg --armor --export AC6F31C5 | apt-key add -
have fun :)
