I tried to install:

  • Ubuntu 20.04
  • Xubuntu 20.04
  • Kubuntu 20.04

But, post install on execute sudo apt-get update, I received the message "Hash Sum mismatch"

What is the problem?

I tried:

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

To solve hash sum mismatch you simply need to enable acquire-by-hash which is available in apt 1.2.0 or newer (if you are using Ubuntu Xenial (16.04) or Debian Stretch, or anything newer, you will be running a version of APT that supports this feature).

To enable acquire-by-hash do the following:

sudo -s
echo "Acquire::By-Hash \"yes\"; ">/etc/apt/apt.conf.d/01byhash
apt update

For a background on apt and other fixes to your problem, see this helpful webpage.


If the above doesn't work for you you can try the following commands:

sudo -s    
apt-get clean
rm -rf /var/lib/apt/lists/*
apt-get clean
apt-get update
apt-get upgrade
