While we would like to provide HTTPS access for all hostnames pointing
to this mirror, Debian prefers having primary mirrors to not have HTTPS for their
If you prefer to access this Debian mirror via HTTPS, please replace
https://debian.ethz.ch/ in your sources.list file.
Sample /etc/apt/sources.list with HTTPS:
deb https://debian.ethz.ch/debian stable main contrib non-free
deb-src https://debian.ethz.ch/debian stable main contrib non-free
Sample /etc/apt/sources.list without HTTPS:
deb http://debian.ethz.ch/debian stable main contrib non-free
deb-src http://debian.ethz.ch/debian stable main contrib non-free
Inoffical Security Mirror
Our security mirror is no official security mirror
and only thought as local cache. See the Debian Security
FAQ for reasoning.
Its updates are not triggered by a push, hence the mirror may be
out of date. If you want to use it, we suggest to use it like this
(you can also use HTTP instead of HTTPS if you want):
Debian 11 "Bullseye" or newer
deb https://security.debian.ethz.ch/ stable-security main contrib non-free
deb http://security.debian.org/ stable-security main contrib non-free
Debian 10 "Buster" or older
deb https://security.debian.ethz.ch/ buster/updates main contrib non-free
deb http://security.debian.org/ buster/updates main contrib non-free
So if this security mirror already has the updated package
mirrored, it's fetched from there as it's the first hit for the newest
version. If not, the newest package is still already available and
fetched from the official servers.
Use at your own risk!
