I've recently installed Kali Linux on a virtual machine and decided to run apt update. How ever every time I try I get this scary looking error.

After doing a bit of googling I found two other people who had the same issue as me.

Kali Linux: apt-get update returns "Hash Sum mismatch" error

https://forums.kali.org/showthread.php?32585-update-error-Hash-Sum-mismatch

Both of which had the same solution that looked promising.

Unfortunately, even after editing /etc/apt/sources.list to use other mirrors from http://mirror.anquan.cl/kali I still get the same error.

Edit (clarification): The solutions I've found online, the links above, all say to change the mirror used in /etc/apt/sources.list which doesn't work for me.

Try using another mirror from the official mirror list and add it to /etc/apt/sources.list.

Like:

deb http://mirrors.ocf.berkeley.edu/kali kali-rolling main non-free contrib

    I should have stated that I've tried this solution already instead of thinking others had the time to read the links I posted, so I clarified this in my post. I already tried this, and with other mirrors. It doesn't work for me.

After a couple of hours more googling I found this post which can explain the problem a lot better than I could.

Kali Linux: apt update returns "Hash Sum mismatch" error

The fix was to:

1: Shutdown the Kali VM

2: Open cmd as an administrator

3: Run bcdedit /set hypervisorlaunchtype off

4: Simply reboot

For those who cannot disable hyper-v, because they must run Docker at the same time, then I had luck with 'Kali Linux 32-bit (PAE) VirtualBox'. No checksum errors there.

I had the same issue and this resolved it for me:

mkdir /etc/gcrypt
echo all >> /etc/gcrypt/hwf.deny
apt update
