Kali Linux Hash Sum Mismatch while doing apt update

https://askubuntu.com/questions/1235914/hash-sum-mismatch-error-due-to-identical-sha1-and-md5-but-different-sha256

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.

VirtualBox – VERR_NEM_VM_CREATE_FAILED

Looks to be an issue if you have Windows HyperV enabled.

Search for and Open up the “Turn Windows features on or off” and make sure “Windows Hypervisor Platform” is unchecked and hit OK to apply it.

Reboot computer and launch VM

Failed to acquire the VirtualBox COM object.

It appears that the issue could be a corrupt VirtualBox.xml file. The one I had did not have anything in it. Removing or moving the file let it create a new one and let VirtualBox actually start.

mv ~/.config/VirtualBox/VirtualBox.xml{,old}

Only problem is that none of the VM’s showed up. Was able to go to the ~/VirtualBox folder in a file browser and launch the vbox file to start the VM

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.

Install VirtualBox Guest Additions for Fedora 22

Install kernel headers, dkms, etc

dnf -y kernel-headers kernel-devel dkms gcc gcc-c++

Reboot the VM

reboot

Mount the Guest Additions by going to menu > Devices > Insert Guest Additions CD image… or you can hit “Host + D”.

The Host key is typically the Right Ctrl(On Windows) or CMD(On OS X) key.

 

Installing the Guest Additions

Via the GUI

Mount the Guest Additions from your file browser, and then launch the “VBoxLinuxAdditions.run”.

You will need root privileges, so either launch your file browser as root, or drag and drop the “VBoxLinuxAdditions.run”, into a root terminal and hit Enter.

Via Command Line

mkdir /tmp/vbox
sudo mount /dev/cdrom /tmp/vbox
sudo /tmp/vbox/VBoxLinuxAdditions.run

If you run into any errors, try ejecting, and remounting the Guest Additions cd.
