Pb apt update Debian9 - Err dep-11 404 Not Found

Contexte : Pb lors de la mise à jour depuis une ancienne Debian 9 testing

Le même pb et solution sur Ubuntu : https://askubuntu.com/questions/786733/apt-get-update-command-not-working-from-xenial-local-Mirror

La solution proposée fonctionne : 

rm /etc/apt/apt.conf.d/50appstream

Autre solution : Désinstaller appstream 

apt-get purge $(dpkg -l | grep appstream | awk '{print $2}')
