Trouble running apt-get update offline

[yetta]

I'm trying to apt-get update kali offline.

I've tried the below two methods

Method 1 from http://www.webupd8.org/2009/11/get-l...endencies.html

sudo apt-get --print-uris update | grep ^\' | cut -d\' > mydownload.txt

mydownload.txt now has:

http://http.kali.org/kali/dists/kali-rolling/InRelease
http://http.kali.org/kali/dists/kali-rolling/main/source/Sources.xz
http://http.kali.org/kali/dists/kali-rolling/contrib/source/Sources.xz

http://http.kali.org/kali/dists/kali-rolling/contrib/binary-i386/Packages.xz
http://http.kali.org/kali/dists/kali-rolling/contrib/binary-all/Packages.xz
http://http.kali.org/kali/dists/kali-rolling/contrib/i18n/Translation-en_US.xz
http://http.kali.org/kali/dists/kali-rolling/contrib/i18n/Translation-en.xz
http://http.kali.org/kali/dists/kali-rolling/non-free/binary-i386/Packages.xz
http://http.kali.org/kali/dists/kali-rolling/non-free/binary-all/Packages.xz
http://http.kali.org/kali/dists/kali-rolling/non-free/i18n/Translation-en_US.xz
http://http.kali.org/kali/dists/kali-rolling/non-free/i18n/Translation-en.xz

Then when I do this from an online Kali

sudo wget --input-file=mydownload.txt

I get:

Method 2 using apt-offline from https://blog.sleeplessbeastie.eu/201...debian-system/. I get similar output as above, I can post if needed.

The output file/signature file in both cases gives packages in the .xz format

My /etc/apt/sources.list file has:

deb http://http.kali.org/kali kali-rolling main contrib non-free
deb-src http://http.kali.org/kali kali-rolling main contrib non-free

As it says I should here

http://docs.kali.org/general-use/kal...t-repositories

uname -a

Linux debian 4.6.0-kali1-686-pae #1 SMP Debian 4.6.4-1kali1 (2016-07-21) i686 GNU/Linux

Q1. The repositories don't have the xz format, only the gz format, so why is apt-get update looking for xz files? Is that why I'm getting the 404 not found message?

Q2. I can download manually, but would rather not, is there an alternative?

Q3. None of the i18n directories exist in the repositories, searching suggests these are locale and language settings, are they important/required for an update?
