Hi! is there an updated manual for Win 11 + WSL2 + Ubuntu 22.04? I have used Win 10 + Ubuntu 20.04 before, but under Win 11 I cannot download the older Ubuntu version from Microsoft shop. Things seem to have changed significantly, because I run into all sorts of errors with my old notes how to set it up.

you could try kali instead of ubuntu

I do have Win 11 + Ubuntu 20.4 This is result of command

wsl.exe -l -o

from PS - there is still no 22.04 for WSL:

Ubuntu             Ubuntu

Debian             Debian GNU/Linux

kali-linux         Kali Linux Rolling

openSUSE-42        openSUSE Leap 42

SLES-12            SUSE Linux Enterprise Server v12

SLES-15            SUSE Linux Enterprise Server v15

Ubuntu-18.04       Ubuntu 18.04 LTS

Ubuntu-20.04       Ubuntu 20.04 LTS

OracleLinux_8_5    Oracle Linux 8.5

OracleLinux_7_9    Oracle Linux 7.9

Try maybe to check the available releses once agian. As you wrote you have checked in the shop - maybe the result was for VM image and not for WSL ?

with 20.04 LTS there was simply no download button in the shop, only for 22.04 LTS https://www.microsoft.com/store/productId/9PN20MSR04DW now it seems I could download 20.04 now that I hopefully just worked the problems out (demoshop booted up finally, didn't try much more yet, so don't want to speak too soon) but interesting that wsl.exe -l -o does not list it
