Tvheadend

I have been following these steps:

Here is a copy from it:

Installing TVHeadend

We’re almost there now. Most articles out there will tell you that you need to build Tvheadend on the Pi. This is not the case, there is actually a repository available to use (see here).
Run curl http://apt.tvheadend.org/repo.gpg.key | sudo apt-key add -
Run sudo nano /<path_to_sources>/sources.list
Add deb http://apt.tvheadend.org/stable wheezy main on a new line in the file
Run sudo apt-get update
Run sudo apt-get install tvheadend – answer 'yes' to any questions and carry out required actions

Good Luck

tried that posting from simpsoncomputers.co.uk on rasperryPi 2 B with a 16GB SD

without any success, may be i'm a bit too much beginner with raspi, but am able to follow that steps quite exactly.
'sudo apt-get update' gave the message :
W: Fehlschlag beim Holen von http://apt.tvheadend.org/stable/dists/jessie/InRelease Erwarteter Eintrag »main/binary-armhf/Packages« konnte in Release-Datei nicht gefunden werden (falscher Eintrag in sources.list oder missgebildete Datei).

Oh, i am on Jessie, so changed that in the 'apt' repo-line.
Could it be a prob with the change to dl.bintray... for tvheadend repo's , or should this work anyway ?

THX a lot for any help, i would like to learn...
