Error installing Bluetooth/BlueZ - Raspberry Pi Forums

hello,
i'm trying install bluetooth with:

code: select all

apt-get install bluetooth bluez-utils blueman

on root, received:

code: select all

reading package lists... done building dependency tree        reading state information... done e: unable locate package bluetooth e: unable locate package bluez-utils e: unable locate package blueman

if do:

code: select all

sudo apt-get update

result is:

code: select all

get:1 http://mirrordirector.raspbian.org wheezy release.gpg [2,256 b]                      get:2 http://mirrordirector.raspbian.org wheezy release [2,256 b]                          ign http://mirrordirector.raspbian.org wheezy release                                      e: gpg error: http://mirrordirector.raspbian.org wheezy release: following signatures invalid: nodata 1 nodata 2

internet connection ok, can ping google.com. surfing on web found other possible solutions, nothing changed:

code: select all

sudo apt-get clean sudo mv /var/lib/apt/lists /tmp sudo mkdir -p /var/lib/apt/lists/partial sudo apt-get clean sudo apt-get update

ideas? lot.
