The discovery thread had errors when running under chroot. Tested on Ubuntu/jammy/22.04 and Ubuntu/noble/24.04

Thread?!

had errors

Can you provide the error message(s) you encountered? I wonder why name resolution would be required, since the WSD protocol usually employs IP addresses for data exchange and not host names. I could imagine that urllib needs a resolver, but I'd like to figure that out.

That example is with the ubuntu 24.04 apt version of wsdd. Same results with 0.8/0.9/latest.
