More WSL than Ubuntu issue.Following a post on https://github.com/microsoft/WSL/issues/8260#issuecomment-1095332420, but in summary, deleted a wsl1 ubuntu repo then next day my wsl2 ubuntu 20.04 wouldn't boot. Unregistered the latter too, but now I can't install either. Just to be clear, it's the 20.04 install that I want.
