Yes, the distro is installed, shows up, and is otherwise usable as expected.

The distro is running, and manually navigating to \\wsl$ shows the expected Ubuntu folder when its running. If its not running that folder does not show up.

Yeah, maybe it's to be expected like that. Similar to computer in a network, how can we access it if the computer is turned off.

It is not. Despite the Ubuntu folder showing up I get the behaviour described in the report.
The Ubuntu share shows in Explorer, but trying to access it fails.

4 years ago My issue turned out to be that via Chocolatey WSL Ubuntu is installed to require admin rights (choco install wsl2 wsl-ubuntu-1804). This is also reflected in that the command line is only accessible when running as an admin. I tried running explorer as admin but that didn't help.
It was solved by:

4 years ago Same symptoms here, can't access \\wsl$\Debian path within Explorer. Nor can I dir \\wsl$\Debian in PS.
Tried another distro (Ubuntu-20.04) from scratch but no difference.
The "network drive" hack works to access WSL files, I mounted \\wsl$\Debian to L: drive.
However it breaks expectations, especially for IntelliJ IDEs (since 2020.2) watching for \\wsl$\ paths to enable WSL-side git.
This leads to a completely unusable git integration, and the following appears in dmesg output :
[ 698.798692] init: (694) ERROR: CreateProcessParseCommon:849: Failed to translate L:\home\username\dev\project\path
Which sounds logical as soon as project is accessed through network drive mount point.
By the way, there is another interesting output in dmesg :

(edit: ignore the Ubuntu stopped, that is from the thread)
powershell (elevated or not), git-bash,chrome, firefox can all access it. within Ubuntu /mtn/wsl shows up and I can access all drives. I tried re-installing the kernal update, Ubuntu, adding a different distro, none worked. Elevated explorer didn't work.
using \wsl\Ubuntu-20.04
Brought up this, but no credentials worked (mentioned in one of the release notes is that both wsl and wsl$ should work)
I'm wondering if something else is interfering with it, maybe a wrong permission or some kind, maybe windows security firewall settings, or network connections and adapter settings. I've got Malwarebytes premium, I have PIA - but it makes no difference if that is active or not. Bitlocker is active. There's a vEthernet (WSL) Hyper-V Virtual Ethernet Adapter set up, along with a couple of other vEthernet ones.
It makes no difference if Docker is running or not

3 years ago Edit: and now, despite everything I said, it seems to work in explorer too (it wasn't working a few minutes ago and this was all after installing updates and rebooting). First time I've ever seen it work... but up to now I was ONLY trying Ubuntu, and only as I was making edits did I dabble more with docker-desktop. I still can't explore it easily, but it's in my "This PC" window now which has never worked.
Summary: With WSL2 and Ubuntu from the MS store, any attempt to explore \\wsl$\Ubuntu fails. BUT cmd.exe /s /k pushd "\\wsl$\Ubuntu" in ~an elevated~ ANY? command prompt gives me a (pseudo) Z: drive with read and write access to my Ubuntu installation. This surprises me, and makes me wonder if it's a clue as to what's going on here.
Actually, reading up on pushd, I see that "When a UNC path is specified, PUSHD will create a temporary drive map and will then use that new drive. The temporary drive letters are allocated in reverse alphabetical order, so if Z: is free it will be used first." Interestingly, if I do pushd "\\wsl$\Ubuntu and then later pushd "\\wsl$\docker-desktop, it sticks with the Z: drive but the map repoints to newly specified system (thus I can't use that to have two drives mapped to two running systems).
Also, any other app ~with elevated permissions~ seems to work with that special Z: drive (e.g., VS Code ~running as admin~).
So, I've been fighting this for a while and I've yet to see a solution, but the admin thing with Chocolatey game me an idea (Note: I'm just using Ubuntu from the MS store, and have installed the WSL2 kernel update, etc. as noted previously).
Whenever I use explorer (running at the usual user level) to browse to \\wsl$ I see the Ubuntu folder, and clicking it results in the old "Attempt to access invalid address" error.
I have a small helper installed (http://code.kliu.org/cmdopen/) that gives me two context menu entries to open a command shell normally or elevated.
If I right click and open command shell, it fails (or fails to do anything at all). But if I select "Open Elevated Command Prompt", after the UAC prompt (as expected) I get a command prompt at Z:
This is interesting as there is NO Z: drive on my system that's normally visible. In fact, I can create a drive mapping to Z: from something else entirely (non-admin) and there's no conflict whatsoever.
I can touch a file there and see it in Ubuntu, and vice versa. So far I still can't use explorer to interact with WSL2 Ubuntu so that doesn't help there.
The full command line, which apparently only works with elevated permissions, is:
cmd /s /k pushd "\\wsl$\Ubuntu"

3 years ago A more concise summary of what seems to work, at least for one running WSL2 OS.
Using:
When I reboot, there are no drives under \\wsl$ in explorer, and the following are what are installed and aren't yet running.
>wsl -l
Windows Subsystem for Linux Distributions:
docker-desktop-data (Default)
Ubuntu
docker-desktopI start Ubuntu (wsl -d Ubuntu or opening the Windows Terminal tab for it).
I explore/refresh \\wsl$ and Ubuntu eventually appears. Clicking on it doesn't work (and it never works, even after the subsequent steps):
I then use my normal windows command prompt and enter pushd \\wsl$\Ubuntu
I can browse Ubuntu via the Z: pseudo drive letter via the command prompt.
Soon, a network location appears in This PC:
I can browse and manipulate the filesystem in explorer via that network location only.
Now interestingly, I can then do a pushd \\wsl$\docker-desktop (as it's also installed) and when I do that the network location's effective target changes to... the Docker Desktop filesystem. If I pushd back to Ubuntu I can again interact with it.
So, is this useful? If you can deal with exploring only one WSL2 filesystem at a time then perhaps. I'm surprised it worked at all as a normal user.
The key oddity here is that as far as the system is concerned Z: isn't really mapped, yet clearly it acts as though it is. And I don't see a way to tell pushd to pick another letter.
Thoughts on this?
Edit: and yes, you can popd your way backwards too...

3 years ago Unfortunately for me there has been no news on this issue. The only new piece of information from the discussion thus far has been that while I can't access \\wsl$\Ubuntu via explorer or command line it is possible to mount \\wsl$\Ubuntu as a network drive and access that.

3 years ago Same issue here. Don't have a clue. I'm trying to install Ubuntu-20.04 on Win 10 (2004, just updated from 1909 since i had this issue) for developing with docker wsl containers. But since windows can't access the linux filesystem even a docker image pull fails.

I am having exactly the same issue.
I can mount \\wsl$\Ubuntu-20.04 as a Network Drive but I cant get it to open on my IDE with just \\wsl$\....
This might be a thing on my works Laptop and maybe because the Ubuntu I am using isnt from the Windows Store.

3 years ago I am now running Version 20H2 (OS Build 19042.662) and every single information in the original report is still unchanged. Would be nice to get some reaction or more hints on what to check.
EDIT: I had the ability to check another device without this issue today, all of the registry information is exactly the same as provided above so it seems to be related to something not currently observed!
