Mandriva 2011, the latest desktop edition of the
popular Linux distribution, was released yesterday. If you have
just installed it, you would have noticed, if you mouseover the
update manager icon, this message: “No medium found. You must add
some media through Software Media Manager.That is just telling you that the package (or update) manager is
not pointing to any remote software sources or repositories. As a
result, no updates can be applied to the system.If you are new to Mandriva, this brief tutorial will show the
simple steps you can take to add (remote) software sources to the
system, plus a few other customizations tips, such as replacing the
default menu.
