Hi,
ich möchte einen TVHeadend Server auf Debian Jessie installieren, ich bin dabei nach dieser Anleitung https://tvheadend.org/projects/tvhea.../AptRepository vorgegangen, allerdings bekomme ich dann folgende Fehlermeldung.

Code:
sudo apt-get install tvheadend
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package tvheadend
Hab sowohl stable-4.2 wie auch unstable ausprobiert, immer das gleiche.

Ich bekomme allerdings auch beim sudo apt update eine Meldung wo ich nicht ganz schlau draus werd wie ich die wieder weg bekomme
