First, I encountered the error below when trying to install new packages.

sudo apt-get install mpack

Err:1 http://http.kali.org/kali kali-rolling/main amd64 mpack amd64 1.6-8.2
  404  Not Found [IP: 80]
E: Failed to fetch http://http.kali.org/kali/pool/main/m/mpack/mpack_1.6-8.2_amd64.deb  404  Not Found [IP: 80]

This is just one example from many packages I'd tried to install. They all failed with the same error (fetching old-non-existent package version)

I noticed that the error said that I could not access to "http://http.kali.org/kali/pool/main/m/mpack/mpack_1.6-8.2_amd64.deb" (on the last line)

So, I tried to access the URL directly on the browser and got 404 not found. What I did next was I went back one step on the URL, so I went to "http://http.kali.org/kali/pool/main/m/mpack/" and found that there was no this "mpack_1.6-8.2_amd64.deb" version. The file that my kali should fetch is "mpack_1.6-17_amd64.deb" (it is there on the mpack path)

I confirm that I have a correct sources.list file and did run the apt update.

my sources.list contains these 2 lines which should be correct and should not be the problem here.

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

The commands that I ran so many times are:

apt update
apt-get update
sudo apt update
sudo apt-get update

So I was so confused why my kali still keeps fetching the old package that it does not exist, and throws the error 404 not found to me?

Or has anybody encountered the same problem?

    @GAD3R thank you for your answer. I did what you suggested but mpack version is still 1.6-8.2 May 23, 2021 at 19:01
  • Can you add to your question the full output of apt-get update? May 23, 2021 at 19:29
  • Is your time set correctly? Also, is this IP address the IP address of the machine you're trying to update? It seems odd that apt would claim be tryng to connect to the HTTP server at this address: 404 Not Found [IP: 80]. When I dial in that address I get Debian Apache Sefver - it works!. I that's your IP address that you're trying to update - try shutting down the Apache server and see it that helps. May 23, 2021 at 20:30
  • @EduardoTrápani Hello Eduardo, I've just updated the apt update result in the question. Looks like my kali connected to the "mirror.kku.ac.th" domain rather than "http.kali.org". Is this behaviour normal? May 24, 2021 at 14:00

    It can be a normal thing if you are using mirrors. May 24, 2021 at 14:03

The http://mirror.kku.ac.th/kali mirror is outdated, providing the old version mpack_1.6-8.2. You can choose a different mirror from Kali Mirrors.

Use the following commands:

printf "%s\n" "deb http://mirror.easylee.nl/kali/ kali-rolling main non-free contrib" |\
sudo tee /etc/apt/sources.list
sudo apt update
sudo apt install mpack
  • OH GOD! IT WORKS! You are a life saver! I thank you four thousand. Anyways, can you tell me how did you know that the mirror is outdated and what is the best mirror to use? May 25, 2021 at 16:52
  • @answer You can check the package version and the last update here mirror.kku.ac.th/kali//pool/main/m/mpack
