[Chakratos]

Having the same issue!
Installed Insider Fast ring.
"wsl --set-default-version 2" and then installing Ubuntu gets me the same error.

Reverting it back to default 1 -> Installing Ubuntu and then using "wsl --set-version Ubuntu 2" still gets me the same error..

[CayoM]

im stuck also. everything was working fine untill this error showed up and now im unable to get it running again. unregistered, removed the distros and now i cant install them again.

i first noticed something was not OK when i suddenly could not clone a git repo from Ubuntu on Windows. Seems like the whole name resolution was messed up. After a reboot i started getting this error.

any help would be highly appreciated.

EDIT: after removing WSL and enabling it again it still not work. I tried what Chakratos mentioned above and was able to install Ubuntu again as wsl1, but still not able to set to wsl2.

EDIT2: System Infos:
Windows 10 Pro
Build 18950.rs_prerelease.190726-1645

[flewsea]

So do I . when i convert wsl 1 to wsl2 . the same error while happen. code is 0xffffffff. system version is 18950

[Andy2244]

Same error, after i did a reboot....

PS C:\> wsl --unregister ubuntu
Unregistering...
PS C:\> ubuntu
Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0xffffffff
Error: 0xffffffff (null)
Press any key to continue...

[scrossan-crown]

I'm having the same issue as @Andy2244 just can't get wsl 2 to work

[GLStephen]

I'm also seeing this. Started running WSL2, got some Docker containers working. Restarted computer. Now this error on everything related to actions in WSL. Started as starting Ubuntu, then I uninstalled and reinstalled Ubuntu and now I can't convert to wsl2.

PS C:\WINDOWS\system32> wsl -e bash
Error: 0xffffffff

Uninstalled, then reinstalled:

PS C:\WINDOWS\system32> docker -v
Docker version 19.03.1, build 74b1e89
PS C:\WINDOWS\system32> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-18.04    Running         1
PS C:\WINDOWS\system32> wsl --set-version Ubuntu-18.04 2
Conversion in progress, this may take a few minutes...
For information on key differences with WSL 2 please visit https://aka.ms/wsl2
Error: 0xffffffff

[scrossan-crown]

I've tried disabling Hyper-v and WSL via Turn Windows features on or off and then re-enabling them but it made no difference

[GLStephen]

Updating to Build 18956.1000 seems to have resolved the issue, though I have no idea why.

[benhillis]

The -1 error indicates an issue creating the virtual network. Those errors tend to be transient.

[CayoM]

Updating to Build 18956.1000 seems to have resolved the issue, though I have no idea why.

i can confirm this too, thx for the info!

Attention: In order to get this update you need to use the fast ring.

EDIT: unfortunately this is happening again...

wsl -l -v
NAME            STATE           VERSION
* Ubuntu-18.04    Stopped         2
PS C:\Users\camor> bash
Fehler: 0xffffffff

now running Build 18956.rs_preselease.190803-1414.

After i switched Docker to WSL 2 Tech Preview and was irritated that i could not see the wsl context running "docker context ls", i rebooted and after that nothing works anymore.... Still getting 0xffffffff.

[Enf0]

I am seeing the same issue after rebooting my machine, on build 18956.1000.

wsl --set-version Ubuntu-18.04 2                                                                                           
Conversion in progress, this may take a few minutes...

[tdaniely]

The -1 error indicates an issue creating the virtual network. Those errors tend to be transient.

I can confirm that I'm seeing the "WSL" switch created and removed in the Hyper-V-VmSwitch logs.

I also see the same behaviour with the Hyper-V Default vSwitch, where I can actually see it appearing and disappearing in Network Connections.

Some searching suggests that this is due to Group Policy blocking Internet Connection Sharing, However I've enabled it manually to see if it is indeed the issue and the adapter device is still being removed.

Is there anywhere where I can find a specific list of configuration requirements for getting the WSL v-switch to work?

Edit:
I've manually enabled ICS and tested that it works between my LAN and WiFi manually. However the v-switch is still being removed. So scratch that.

v-switch logs: https://pastebin.com/3ReMcxtc

Last edit:
After manually going over basically everything on my laptop, I've eventually found that it was the Acrylic DNS Proxy service I'm using. The service was grabbing port 53 and preventing the ICS service from binding to it.
