The sources tarballs and the Debian/Ubuntu packages could be directly downloaded from the Download Area.

The Ubuntu packages could be downloaded by adding the Arakhnê.org package source into your /etc/apt/sources.list file.
The line to add is:

deb http://download.tuxfamily.org/arakhne/ubuntu distname universe

• intrepid-arakhne
• hardy-arakhne
• gutsy-arakhne
• feisty-arakhne

The packages are signed by a GPG public key. You must add this key into your apt key list to avoid warnings. To proceed use one of the following methods:

1. Download the public key from the download area and add it into the apt key list:

   wget -q http://download.tuxfamily.org/arakhne/public.key -O- | sudo apt-key add -

2. Import the public key into your local key repository:

   $> gpg --keyserver www.keyserver.net --recv-keys 0xBA62BC7E

   or

   $> gpg --keyserver keyserver.mobrien.net --recv-keys 0xBA62BC7E

   Add the imported public key into the apt key list:

   $> gpg --export -a 0xBA62BC7E | sudo apt-key add -

3. Import the public key into your local key repository:

   $> gpg --keyserver keyserver.mobrien.net --recv-keys 0xBA62BC7E

   the imported public key into the apt key list:

   $> gpg --export -a 0xBA62BC7E | sudo apt-key add -
