"microk8s install" fails on Windows 10 version 2004

“microk8s install” fails on Windows 10 with the following message:

An error occurred when trying to execute 'sudo ping -c 1 snapcraft.io' with 'multipass': returned exit code 1.

But, can install microk8s within microk8s-vm manually.

One quick question before we launch … Would you like to help
the Multipass developers, by sending anonymous usage data?
This includes your operating system, which images you use,
the number of instances, their properties and how long you use them.
We’d also like to measure Multipass’s speed.

Try disabling Realtime protection on Windows Defender (in Windows 10 Options search for “Virus & Threat Protection” - under “Virus & Threat Protection Settings” click “Manage Settings”. Turn off Realtime Protection.).

Unless you run a Registry change the Realtime Protection setting is re-enabled when Windows is restarted. You should be able to install Microk8s successfully - Windows Defender does not appear to affect it once it is installed. For performance reasons I would not use the Microk8s embedded Kubectl - you are better off installing the native version (use Chocolatey Package Manager to install it if you need it: choco install kubernetes-cli ).

@mattscottuk Thank you for your suggestion. I’m going to try your solution when I get this issue again. Because I upgraded my machine to Windows 10 version 20H2 and not using the microk8s currently. So I will close this issue.
