    Kali 2020.2 OVA VIRTUALBOX - HASH SUM MISMATCH

    after starting up Kali VM for the first time and running "apt update && apt -y full-upgrade" I get "http://kali.download/kali kali-rolling/main amd64 metasploit-framework amd64 5.0.88-0kali2 Hash Sum mismatch"

    Please help me find a solution
    Sources.list:


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

    It's July 2020 and still I haven't found a reasonable solution to this. The only way I can effectively run Kali is through an older 2018 iso and updating it from there.

    I had this problem on my ubuntu laptop. Must be an external error. @metaslpoit-framework

    Found the solution:

    $ sudo bash

    $ mkdir /etc/gcrypt
    $ echo all >> /etc/gcrypt/hwf.deny
    $ sudo apt-get update

    Just saw this post after posting a new thread on same issue (my apologies)
    whatever mirror I choose, apt reports a different hash of Packages.gz, but the actual hash from each when downloaded outside of apt matches the expected hash
    apt bug?

    Holy ****, this worked! What, exactly, does this do? And are there other security implications to consider?

    Thank you -- this worked for me, too. I am running Kali2020.2a 64-bit on Oracle VirtualBox 6.1 and Win 10 Pro Hostt OS.

    All this does is disable hardware optimisation on the gcrypt library. (source: https://www.gnupg.org/%28es%29/docum...iguration.html)

    It disables hardware optimisations on libgcrypt. (source: https://www.gnupg.org/%28es%29/docum...iguration.html)
