Add-AppxPackage .\Ubuntu.appx


First Run and Installation

Win+r Ubuntu

Set WSL DNS to Google DNS (default is a Windows generated, which doesn't always work)

Change the DNS to Google's DNS

sudo nano /etc/resolv.conf


# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateResolvConf = false
nameserver 8.8.8.8

Avoid windows from changing the DNS server again:

sudo nano /etc/wsl.conf 


[network]
generateResolvConf = false

sudo apt update
sudo apt upgrade -y

SSH Host Key Checking

If you want to avoid issues on connecting via SSH because the the keys are not added, go to:  

sudo nano /etc/ansible/ansible.cfg

Extra - Convert Install Machines to WSL2

If you already had WSL installed and some distros and want to convert then, first check your distros and versions:
