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}')
