Answer 1

1. https://download.01.org/gfx/ubuntu/16.04/main/dists/xenial/InRelease:

alle haben solche Probleme (ich habe auch) - Intel ist faul, den richtigen Schlüssel zu erstellen - keine Sorge

https://01.org/linuxgraphics/forum/graphics-installer-discussions/new-ubuntu-16.04-packages-use-unknown-key-again

2. Befehle ausführen:

   wget -q "http://deb.playonlinux.com/public.gpg" -O - | sudo apt-key add -

   sudo wget http://deb.playonlinux.com/playonlinux_trusty.list -O /etc/apt/sources.list.d/playonlinux.list

3. sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/strycore/xUbuntu_16.04/ /' > /etc/apt/sources.list.d/lutris.list"

   wget -nv https://download.opensuse.org/repositories/home:strycore/xUbuntu_16.04/Release.key -O Release.key

   sudo apt-key add - < Release.key

   sudo apt-get update

Answer 3

Gehen Sie einfach zur GUI-Update-Funktion und deaktivieren Sie alle „anderen Softwareprogramme“. Das Aktualisieren des Caches funktioniert jetzt einwandfrei, ebenso „sudo apt update“.
