@misaya98 can you check if this is the same known issue with WSL reported here ?

Starting to look like WSL2 v1.2.0.0 brought the issue back - facing the same here after the update.

I'm facing the same issue with wsl version 1.2 and the latest kind version. I know folks have mentioned that reverting to v1.0.3 of wsl fixes the issue for them. Are there clearly defined steps in order to revert to the wsl version?

[BenTheElder]

Sorry, Currently we only have WSL2 documented by user contribution: https://kind.sigs.k8s.io/docs/user/using-wsl2/
We don't use this and there's no windows CI #1529

[asheeshv]

Thanks for the response Ben. I'll take a look and determine the way to lower the wsl2 version. I know for sure KIND has worked fine for me on my windows setup using docker-desktop.

For those who come across this issue as of today, run the following on an admin shell:
wsl --update --pre-release

WSL2 v1.2.3/1.2.4 (pre-release) have the issue above fixed.

[BenTheElder]

Thank you very much @igordcard! #3180 is pinned and links back to your comment

@BenTheElder thanks for looking into this.

Unfortunately I cannot run wsl --update --pre-release as it leads to an error (To install this application you need either a Windows developer license or a sideloading-enabled system. Error code: Wsl/UpdatePackage/0x80073cff).

I will try to fix this and, if I can't, I'll wait for the next WSL release version.

I'll update the issue as soon as I can.

[BenTheElder]

@zapho maybe you could downgrade instead?

I think that would be:

wsl --update --rollback
