Debian Mirror / Another fix for hashsum mismatch

At work I am running a debian mirror for a bunch of client machines. I needed packages from the backports, so I added the backports to mirror and got this nice error:

W: Failed to fetch ftp://$SERVER_AT_WORK/debian-backports/dists/jessie-backports/main/binary-amd64/Packages Hash Sum mismatch

Turns out, the old mirror structure from debian wheezy cannot be used for a jessie-mirror, you need to use the same directory structure as on the offical mirrors (ftp://$SERVER_AT_WORK/debian/dists/jessie-backports).

For a complete mirror you can use this script:

	#!/bin/bash
	# configuration
	MIRROR='ftp.de.debian.org'
	ARCH='i386,amd64'
	SECTIONS='main,contrib,non-free,main/debian-installer'
	RELEASE='jessie'
	MIRRORDIR=/srv/ftp
	# end of configuration
	DISTS="${RELEASE},${RELEASE}-updates,${RELEASE}-backports"
	COMMONOPTS="-v -a ${ARCH} -s ${SECTIONS} --i18n --passive --ignore-missing-release --ignore-release-gpg --slow-cpu"
	mkdir -p $MIRRORDIR/debian
	mkdir -p $MIRRORDIR/debian-security
	debmirror $COMMONOPTS -r debian -h $MIRROR -d $DISTS $MIRRORDIR/debian
	debmirror $COMMONOPTS -r debian-security -h security.debian.org -d $RELEASE/updates $MIRRORDIR/debian-security
