fetch linux headers problem on beaglebone black rev B (debian) although it works on rev C distro

I got 2 BBB one revision C and the other B. I’ve installed the latest debian distribution on both, then upgrade the kernel through the script present in /opt/script/tools. On the C in order to compile a module I’ve succeeded to fetch the linux header using

apt-get install linux-headers-$(uname -r)

On the B that does not work, while I’ve inserted the following line in /etc/apt/source.list

deb [arch=armhf] http://repos.rcn-ee.net/debian/ wheezy main

line which is present on revision C but not revision B

I get :

E: Unable to locate package linux-headers-3.8.13-bone67

E: Couldn’t find any package by regex ‘linux-headers-3.8.13-bone67’

and I have no idea to correct this, anybody could help ?

thanks

Well, did you run "apt-get update" after adding the repo to
/etc/apt/source.list?

You'll need the key too:

wget -qO - https://repos.rcn-ee.net/debian/conf/repos.rcn-ee.net.gpg.key

sudo apt-key add -
