Como instalar "Agregar o Quitar Programas" típico de Ubuntu en Jolicloud.
Jolicloud is a new OS for netbooks that offers, among other things, a software installer based around Prism applications (basically, webpages on a stripped down browser) and a few system staples like VLC.

While the idea is good there’s not a lot of software available through their system yet and typing apt-get in a terminal, while easy, can get confusing for someone used to a GUI. The alternative, Synaptic, a graphic package manager, offers way too many alternatives and also ends up being confusing to a new user.
Ubuntu solved this dilemma by implementing a very simple application installer that anyone can use. Jolicloud doesn’t include it but it’s very easy to add it.
Open a terminal window (Accessories > Terminal in the launcher or press [ALT] + F2] and enter gnome-terminal) and copy&paste the following command:
sudo apt-get install gnome-app-install
Write your password when it asks for it and that’s it.

Note: The shortcut for the app should appear in Accessories (logging off may be necessary) but if not, it can be added via Preferences > Main Menu.

Update: Add/Remove seems to have been added to the default installation of jolicloud alpha 2c.
