@sdancer75 Maybe you just did forget one step of the installation process?
I myself missed one important point during installation of Docker Desktop for Windows and had the same problem that you describe: My Ubuntu distro did not appear in Docker Resources settings and it stated that I wouldn’t have any WSL 2 distros (which was obviously not correct).
Fortunately (for me) it was not necessary to uninstall and reinstall the Ubuntu distro - there is a much easier way:
I could resolve this issue for me by adding my Windows user account to the group docker-users - just as it says in the installation instructions for Windows:
If your admin account is different to your user account, you must add the user to the docker-users group. Run Computer Management as an administrator and navigate to Local Users and Groups > Groups > docker-users . Right-click to add the user to the group. Log out and log back in for the changes to take effect.
After doing that, everything worked as expected and I was able to see my Ubuntu in Docker settings as a WSL2 distro.
So before trying anything other you should first check if your user is a member of the group docker-users.
