What does unity do the very first time you create a project? (or load one)

This is my first post. I ve just installed unity and I would like to create the simplest project. This is the very first time I am running unity

When doing this, I got a progress bar saying “Unity Package manager” “Starting Server”
My question is, what is happening here? Does Unity have to connect to a server to create a project? or to load one? Why?

Thanks.

(My problem is that it takes forever)

Ummmm. This is a new 2017 thing. I have no idea.

thanks
Anyone have any idea on what is happening?

No. Haven’t run into this problem with the latest releases. Any chance you can upload a screenshot of it happening?
