Fix WSL ubuntu problems

Running that Linux subsystem under windows 10 got some problems, as expected.

I could ping to external sites by name, so DNS worked and some networking. But downloading updates or connecting to those websites I could ping failed.

Solution (for me) was to downgrade from WSL2 to WSL1 for this instance.

Show the current WSL versions per image:

wsl -l -v

Downgrade by named image (will take some minutes and popups will appear, which I clicked cancel)

wsl --set-version Ubuntu 1

And check again

wsl -l -v
