[anjannath]

The release artifact's sha256sum do not match.

What happened: Sha256sum check in the intall.sh failed and i wasn't able to start microshift

What you expected to happen: be able to setup and run microshift by using ./install.sh

How to reproduce it (as minimally and precisely as possible):

1. Clone repository and cd into it
2. run ./install.sh

Environment:

• Microshift version (use microshift version):
• Hardware configuration: rhel 8 VM
• OS (e.g: cat /etc/os-release): rhel 8.4
• Kernel (e.g. uname -a): Linux maximus100.localmachine.com 4.18.0-305.12.1.el8_4.x86_64 Init #1 SMP Mon Jul 26 08:06:24 EDT 2021 x86_64 x86_64 x86_64 GNU/Linux
