package libc6:amd64 2.31-0ubuntu7 failed to install/upgrade: installed libc6:amd64 package post-installation script subprocess returned error exit status 1

I was trying to upgrade ubuntu 18.04 LTS to the latest version on 15-Apr-20, using commands from this website >> https://www.zdnet.com/article/how-to-upgrade-to-ubuntu-linux-18-04/

The fact that I was upgrading Windows 10 Linux sub-system that was downloaded from Windows Store really is a concern.

From the provided website, the most recent command I executed was:

$ sudo do-release-upgrade -d

So I went from bionic to focal is another concern.
