Solana Test Validator Fail

These are the steps that I was able to fix the error:

Incompatible CPU detected: missing AVX2 support. Please build from source on the target

My setup: Ubuntu 20.04 Intel(R) Core(TM) i7-2670QM

First install the following packages

sudo apt install libudev-dev  
sudo apt install libssl-dev
sudo apt install clang

1. Download and extract Source code (tar.gz)
2. In the same directory run: ./scripts/cargo-install-all.sh . and wait til complile finish.
3. Run solana-test-validator
