bluetooth installation

Hi

I want to install bluetooth-support with this command

sudo apt-get install bluetooth bluez blueman

and get the following error message

Reading package lists… Done

Building dependency tree

Reading state informations… Done

E: Unable to locate package bluetooth

E: Unable to locate package bluez

E: Unable to locate package blueman

 What am I doing wrong?

I use IOT2050 with example-image.

Thanks
