Astade for Ubuntu is available at Launchpad. There you can find two package archives for stable releases and for daily builds. Just follow the Launchpad instructions on how to add the archive of your choice to your system.

Here is the short version for the stable release archive:

1. sudo apt-add-repository ppa:astade/release
2. sudo apt-get update
3. sudo apt-get install astade

That's all.

Behind a proxy you need:

export http_proxy=http://<proxy>:<port>
export https_proxy=http://<proxy>:<port>
sudo -E apt-add-repository ppa:astade/release

For adding the ppa.

If you want to install Astade on an Ubuntu computer you have to complete three steps:

1. add “apt.astade.de” to your package sources
2. add the Astade public gpg key to your keyring
3. install Astade

• Select “System” → “Administration” → “Software Sources”. Select the tab “Third-Party Software”.
• Press the “Add” button
• Instert the Astade repository as new source, e.g. “deb http://apt.astade.de hardy main” (or intrepid , or jaunty, or …)

This works best from command line. Type the command:

curl http://apt.astade.de/dists/key.asc | sudo apt-key add -

Now just install, as you usually install packages. Ether with synaptic packet manager or from command line by typing:

apt-get install astade
