Kali Linux Hash Sum Mismatch while doing apt update


Looks like the problem is caused by the Windows Hypervisor Platform. Work around is to disable it.

In the Start menu search for “turn Windows features on or off”

Once open, disable “Virtual Machine Platform” and “Windows Hypervisor Platform”

Disable Virtual Machine Platform

You will need to reboot after it finishes.

Install VirtualBox Guest Addition for Kali Linux

Boot up the virtual machince

Insert the “Guest Additions CD Image…” from the Devices menu

In the VM, open up Files/Nautilus or Dolphin and find the CD. Open a terminal in the same directory and execute the auto run script

sudo sh autorun.sh

It should pop up another window to install the guest additions. After it is installed, you’ll need to reboot the VM for the new changes to take effect.

Set Bash as users default shell

You can change the default shell for a Linux user with the following command.  Change “/bin/bash” to whatever shell you want and replace USERNAME with the Linux user.

chsh /bin/bash USERNAME

Enter in the users password and then log out and back in and the users shell will be whatever shell you specified.  In this case bash.

You can also do this by manually editing the /etc/passwd file.  Find the user by their username, and then replace the last part of the line with the new shell path.

Some Linux distributions (like Kali Linux) use /bin/sh as the default shell for new users.  Changing it to bash makes the shell a little more usable.

apt-get update

And dist upgrade

apt-get dist-upgrade
