Windows 10: WSL 2 apt says network is unreachable

I just set up a fresh install of Windows 10 on a brand new disk. I then followedthis official guide for setting up WSL 2, and installed the latest Ubuntu 20.04 from the Microsoft Store. With this launching correctly, the first thing I tried was a `sudo apt update` so that I could start installing software, but this failed saying "Network is unreachable":




I browsed the web for a solution and saw work that IPv6 could be the culprit, but even after disabling IPv6 on the WSL adapter and my ethernet adapter, the problem persists.


I don't understand why installing WSL with the official instructions on a brand new install of Windows 10 would have any issues. I am unable to install any software in WSL due to this issue.

How to configure WSL Ubuntu (or any WSL distro) to use a NAT virtual network

I've installed WSL Ubuntu on my Windows 10 laptop and it is running fine.

However, it is not able to access anything on the Internet at port 80 and so forth. I cannot use apt package installer to install any software at all.

My host laptop Windows environment has no problem, of course, with Internet access.

Info I've gleaned is that WSL is being blocked by a firewall. Am using Kaspersky as mandated by internal corporate policy. I've added an exception rule for WSL but that has no positive effect on the problem. Additional info I've gleaned is that others have
had same experience - unfortunately this doesn't allow programs running in WSL virtualization any access out to the public Internet.

The latest info I could find is that WSL just flat out won't work with several prominent Windows firewall apps unless they are disabled of even uninstalled (not a possible option for me).

So I followed these instructions and created a NAT virtual network:
Set up a NAT network

Got that created with no problem and it shows up as eth3 interface on my laptop.

Remaining instructions at the above link talk about how to get Docker for Windows and other Hyper-V VMs to use this NAT. However, I can't find anything that instructs how to setup WSL to do so. WSL evidently can't be managed in same manner as other Hyper-V
VMs.

Presumably the iptables or ip command to setup routing could be used to do this in the Ubuntu Linux environment, but that is where am appealing for help from anyone that knows how to do this in respect to WSL.

 

Cannot upgrade installed distros in WSL to version 2

After installing the Win10 2004 build 19041 update (running winver shows "version 2004 (OS build 19041.388)", I've tried to upgrade a couple of installed distros I had in WSL version 1 to WSL version 2 following the instructions at https://docs.microsoft.com/en-us/win.../install-win10. All the steps in the instructions compete successfully, up to the point where I try to change the WSL version of one of the installed distros to 2 at which point I see the messages below:

Code:

I have enabled the Virtual Machine Platform feature (it shows as on with a tick against it in Control Panel Windows features), Intel-vt virtualization is enabled in the BIOS, and running msinfo32 shows, at the bottom of the system summary listing:

Code:

I also tried installing another distro with the WSL default version set to 2, but attempting to launch it shows the error:

Code:

Any suggestions on how to get around this problem? From what I've read, WSL2 gives worthwhile speed increases over WSL1, and so is worth using if I can get it to work.
