On installing Ubuntu as guest from Windows Host, if you got an error Update Hash Sum Missmatch Fix, this is a fix for that
Based on https://askubuntu.com/a/1242739
Try this before running apt:
$ sudo bash
# mkdir /etc/gcrypt
# echo all >> /etc/gcrypt/hwf.deny
Because apt use sha256 method from libgcrypto20, but optimized too much. We can deny this opt. using configuration file /etc/gcrypt/hwf.deny.
Then run apt update` and ` apt upgrade
