Hi,
i am very new to the whole RPI world.

My initial Problem is, to get a Bluettooth Keyboard working with my RPI 2
I read a few tutorials, and all state that i need the BT Package first. (i think the name is bluez). So i read a tutorial on how to load packages on a RPI. They all say to use the command apt-get ....

But in the Xbian FAQs there is this warning about NOT to use apt-get, but instead use the Xbian-config.
In the Xbian-config via SSH i find the "Packages", but in the Packages menu i can not find the "BT package"

So my question is simple. How do i get it?

Thx in advance.


edit: or is it only the specific "apt-get dist-upgrade" command i shall not use. Normal apt-get commands are ok? If that is the case, i guess i get it, but the FAQ title is a little confusing
