[tksh164]

"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.

Hi @tksh164,

Could you please try the steps listed here https://multipass.run/docs/troubleshooting-networking-on-windows and let me know if you can run micrko8s install afterwards, please?

Thanks,
Joe

Thank you @joedborg,

I did purge existing microk8s-vm, after that remove HNS network and reboot. But, the result was the same. Also, C:\WINDOWS\System32\drivers\etc\hosts.ics on my machine had only one microk8s-vm entry.

Hey @tksh164,

Thanks for trying that, sorry it didn't fix the issue.

What happens if you try:

multipass shell

(this will create a VM called primary)

Once you get a shell inside the VM, can you please try

ping 8.8.8.8
ping snapcraft.io

And let me know the results, please?

(You can then delete and purge the primary VM).

Thanks,
Joe

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_ ).

[tksh164]

@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.
