Hash Sum mismatch on apt update

Hi,

I just imported Kali onto Virtual Box. I ran

Code:

---

apt update && apt upgrade

---

which was interrupted by the system freezing. After rebooting I had to

Code:

---

dpkg --configure -a

---

and then proceeded with the update. Now

Code:

---

apt update

---

results in a Hash Sum mismatch error.

Code:

---

I already tried:

• Code:

  ---

  apt clean

  ---

• Code:

  ---

  apt autoclean

  ---

• Code:

  ---

  rm -rf /var/lib/apt/lists/*

  ---

• Changing the default mirror in sources.list
• Waiting for 10h

This is a second time I' trying to install the VM on VirtualBox (on VMware it went pretty smoothly). The first time the system froze and something broke to an extend I decided to just reinstall (ping did not have SUID for example). I do not want to reinstall again...

Hi

did you found any fix or workaround for this. I am also struggling with the same issue

Still no solution for this?

This worked for me! (Also, VMware wasn't working previously)


Shut down Kali VM.
Run bcdedit /set hypervisorlaunchtype off in Command Prompt as administrator.
Reboot.

I, too, am having the same issue. I've search the web for resolutions and have tried every one.

I used the olderversions for about 2 week.
After that i fired up this machine and the problem was gone, without any changes being made on my side. As it was suggested in many other threads, looks like there was something with the Mirror at that time.

Here's the solution that worked for me:

Nothing worked for me so I created workaround.
This script changes expected hash to recived one. I know that's not perfect and totally not for prod but if you are in hurry it can help. Python 3.6+
