I get the above error running this tutorial

after dfx build. It then hangs.

I am using Windows 10 WSL2 and Ubuntu 20.04.3 LTS

This message is just a red herring, and safe to ignore (unless you are in a production environment).

The above message is from dfx start, not dfx build.

Have you successfully run dfx start previously on this machine? Or is it the first time you tried using dfx?
Which version of dfx are you using?

dfx 0.11.2

The above message is from dfx start , not dfx build.

No, it was from dfx build.

I had previously run dfx start --background.

I had also previously successfully worked through the Explore the default project tutorial.

I repeated this tutorial in an Ubuntu VM instead of Windows WSL and it worked. So I suspect WSL is best avoided.
