    I've encountered "Hash Sum mismatch" too, most likely the mirror is bad.

    So, visits http://http.kali.org/README.mirrorlist with your web browser.

    Then choose another mirror, and replace the host with this new mirror in `/etc/apt/sources.list`, e.g.:

    deb http://<your new mirror>/kali kali-rolling main non-free contrib
    Note that if the mirror too slow, you don't have to waste your time, you should stop it by Ctrl+C and change it to another mirror.

    This solved my problem

    <Hash Sum Mismatch> is actually one of the most irritating problems I've faced. To solve this problem just change the mirror you have been using.

    Go to this site http://http.kali.org/README.mirrorlist for the list of mirrors. You will also find some suggested mirrorlist near your region (Country).
    You can try using one of those first.

    Then, first Open your source file "/etc/apt/sources.list". You might see your file similar to this.

    Code:
    # 
    
    # deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160830-11:29]/ kali-rolling contrib main non-free
    
    #deb cdrom:[Debian GNU/Linux 2016.1 _Kali-rolling_ - Official Snapshot amd64 LIVE/INSTALL Binary 20160830-11:29]/ kali-rolling contrib main non-free
    
    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
    For eg. lets use http://ftp.hands.com/kali/README

    Replace
    deb http://http.kali.org/kali kali-rolling main contrib non-free
    with
    deb http://ftp.hands.com/kali kali-rolling main contrib non-free
    we just replace the part in between http://<some link part>/kali

    Replace similarly if you want deb-src package too.

    In this link
    deb http://http.kali.org/kali kali-rolling main contrib non-free
    what actually happens, is the bold part is replaced with the nearest and best mirror according to your region.

    The problem was actually with the mirror used. Just change to other mirroe as given in the link if any problem provided by one.

    Hope it helped.
