Error when converting a distribution from WSL1 to WSL2

[warpdesign]

After installing WSL2 I tried to convert an existing WSL1 to WSL2 using this command:

C:\Users\warpd>wsl --set-version Ubuntu 2

And after a long time (~20 minutes) I got the following error:

La conversion est en cours. Cette opération peut prendre quelques minutes...

During the conversion my machine slowed down a lot: it seems the process was using most of my 8Gb:

I am running Windows 10 Pro version 2004 (19041.264) on a Surface Book.

I think you have to use Powershell. for that command to work here

I think you have to use Powershell.

No cmd.exe is fine. The linked documentation is just expository.
