Impostare sources.list di Debian Jessie
Date che Jessie è fuori supporto, le source APT standard danno questo errore:
W: Failed to fetch http://ftp.debian.org/debian/dists/jessie-backports/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ftp.debian.org/debian/dists/jessie-backports/contrib/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
Per correggere, impostare:
vi /etc/apt/sources.list
deb http://ftp.it.debian.org/debian/ jessie main contrib non-free deb http://security.debian.org/ jessie/updates main contrib non-free #deb http://archive.debian.org/debian jessie-backports main contrib
Poi
vi /etc/apt/apt.conf
Acquire::Check-Valid-Until "false";
L'errore è corretto:
apt-get update
