Answer 1

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

у всех такие проблемы (у меня тоже есть) - Intel лень создавать правильный ключ - не переживай

2. запустить команды:

   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
